Description

TECHNICAL FIELD [0001] The present invention relates to a constant-temperature and humidity-controlled air-conditioner equipped with a separate type heat pipe,

The present invention relates to a thermo-hygrostat equipped with a separate type heat pipe and a control method for the purpose of using cold of outside air when the outside air temperature is lower than room temperature.

In addition to the basic refrigerator cooling circuit of the known conventional thermostat,

A heat pipe evaporator circuit comprising a separable heat pipe evaporator, a three-way electromagnetic valve, a condenser of an evaporator / condenser heat exchanger, a receiver, and a liquid pump,

And a heat pipe cooling circuit configured by including a heat pipe condenser and a check valve in the heat pipe evaporator circuit,

The refrigerator cooling circuit and the heat pipe evaporating sub-circuit are operated in the summer according to changes in the outside air temperature,

In the winter, only the heat pipe cooling circuit is operated,

In the middle season, the refrigerator cooling circuit or the heat pipe cooling circuit can be operated independently or in combination through a control unit.

The liquid pump circulation method applied to the constant temperature and humidity unit equipped with the separate type heat pipe eliminates the channel closing in the heat pipe by the refrigerant gas or the refrigerant liquid, thereby improving the heat efficiency and enhancing the heat exchange ability.

In addition, the thermal efficiency of the heat pipe is superior, so that the heat pipe cooling circuit can easily use the cold air even in the middle season where the temperature difference between indoor and outdoor is relatively low, such as 2 ~ 3 ° C, Saving thermo-hygrostat.

Generally, air conditioner is a room air conditioner which keeps conditions such as temperature, humidity, bacteria, smell, air current in the room suitable for the purpose of use in the room, To make it comfortable.

The comfortable air condition for a person is influenced by various conditions such as weather condition, clothes, living level, health condition, and therefore it is not constant value, but it is 26 ~ 28 ℃ in summer temperature and about 50% It is usually aimed at 20 ~ 22 ℃, relative humidity about 40%.

However, such values are not absolute, and in order for the workplace, warehouse, laboratory, computer room, etc. of the factory to fully achieve its function, the most suitable State.

For example, in a tobacco plant, when the leaves are chopped, the temperature is lowered to increase the relative humidity so as not to be dried and to prevent the chocolate from melting.

In the semiconductor manufacturing plant, the dust is reduced extremely, and in the physiology laboratory, the flow of air is slowed in consideration of the influence of wind on life.

Air conditioning is used to ensure that the quality of the products produced is not uneven or defective.

In particular, when it is intended to apply to industrial applications such as a product process requiring a constant temperature and humidity or a storage process, it is necessary to control not only heating and cooling but also humidity.

The constant temperature and humidity air conditioner capable of air conditioning is a device for maintaining the temperature and humidity of the indoor space at a predetermined value. The device includes a cooler for supplying cold air, a hot air fan for supplying warm air, and a humidifier for maintaining indoor humidity.

A refrigerator cooling circuit composed of an evaporator, a condenser, a compressor and a valve is formed to generate cool air from the evaporator, and warm air generated from the heating wire is supplied to the indoor space through a blower fan, Therefore, the humidity of the indoor space is controlled.

That is, the known thermo-hygrostat is used to maintain the set temperature and humidity at all times. It is installed and used in various fields such as rooms equipped with precision control devices sensitive to temperature and humidity, rooms equipped with expensive communication devices, laboratories and computer rooms It is a device that prevents malfunction of various devices and cooperates with stable cooling space.

In such a conventional thermo-hygrostat, a control unit, components necessary for cooling and heating, and parts necessary for dehumidification or humidification are integrally combined into a single system, and when the temperature or humidity of the room is out of the error range or more than the set temperature or humidity, , The control unit automatically performs cooling, heating, dehumidification or humidification operation.

On the other hand, in such a thermo-hygrostat, the refrigerator cooling circuit is operated to maintain the set temperature of the room, but even when the outside temperature is very low as in the winter season, natural cooling is not used at all and the refrigerator cooling circuit continues to operate. There is a problem.

With respect to the energy-saving thermostatic / hygrostatic device of the present invention, there has been disclosed a technique of "an energy-saving thermostat and control method using a cooling tower cooling water and a control method thereof" proposed in Korean Patent No. 10-0933515.

In the above-mentioned patent, the condenser cooling water outlet temperature, which is heat exchanged in the summer refrigerator cooling circuit, is set to 36 to 38 DEG C, and the cooling water outlet temperature that is heat-exchanged in the cooling tower is set to 31 to 33 DEG C, This is a common and universal technology that can be judged to follow this norm.

If the outside temperature of the outside temperature detection sensor is set to 15 ~ 17 ℃ or more, it is selected as the summer season. If it is less than 15 ~ 17 ℃, it is selected as the mid season and winter season mode. It switches to winter season mode. According to the general rule of the above-mentioned design of the heat exchanger, if the temperature difference of 5 ° C is set, the outside temperature of the cooling tower should be 1 ~ 3 ° C for the heat exchanger to be 6 ~ 8 ℃.

The monthly average temperature of standard weather data for 17 cities in Korea is 5.9 ℃ in December, 3.4 ℃ in January, 5.3 ℃ in February, and 9.1 ℃ in March. It is a disadvantage that it is extremely limited to fully utilize the cold atmosphere because it can not enter.

Also, the above-mentioned patent is applied to a water-cooled thermo-hygrostat, which is not applicable to an air-cooled thermo-hygrostat.

In the case of the water-cooled thermo-hygrostat, numerous power cables and communication cables are laid on the floor of the electronic equipment room such as the computer room. Further, installing the cooling water coil in the indoor unit further increases the risk.

In addition, it is difficult to control the water for prevention of frost damage in the winter season, and the additional installation of the cold water coil increases the cost, and there is a disadvantage that the power consumption of the fan motor becomes large due to the static pressure loss when circulating air passes, or the motor itself becomes large.

The present invention relates to a thermo-hygrostat according to the present invention, which is a general component of a conventional thermo-hygrostat, such as an indoor temperature sensor, a humidity sensor, a control unit, a compressor, a condenser, an expansion valve, a plate or shell and tube evaporation / condensation heat exchanger, In addition to the basic refrigerator cooling circuit provided,

In addition, the liquid pump 200, the detachable heat pipe evaporator 201, the three-way electromagnetic valve 202, the receiver 204, the separate heat pipe condenser 205, the check valve 206, ), A refrigerant liquid temperature sensor (B), and a control circuit.

At this time, the heat pipe cooling circuits 201 and 205 may be installed in the body of the thermo-hygrostat unit, or may be separately provided to the outside in order to facilitate installation.

However, the outlet piping of the heat pipe cooling circuits (201, 205) is connected to the inlet of the condensing section of the evaporating / condensing heat exchanger constituting the refrigerator cooling circuit, and the outlet pipe of the condensing section is connected to the receiver.

A refrigerant liquid temperature sensor (B) is installed in the receiver (204) to control the refrigerator cooling circuit (10).

The liquid pump 200 functions to forcibly circulate the refrigerant remaining in the receiver 204 to the separable heat pipe evaporator 201.

The liquid refrigerant supplied to the separable heat pipe evaporator 201 is evaporated through the heat exchange process to cool the room.

FIG. 2 is a schematic view showing a winter operation mode of a constant temperature and humidity air conditioner equipped with a separate type heat pipe heat exchanger. In the winter season, only the heat pipe cooling circuit 30 is operated.

2, during the winter season, the liquid refrigerant flowing into the receiver 204 is forcibly circulated through the liquid pump 200 to the separable heat pipe evaporator 201,

The liquid refrigerant transferred through the liquid pump 200 is subjected to a phase change to the gaseous refrigerant by heat exchange of the separable heat pipe evaporator 201 and then to the separable heat pipe condenser 205 through the three- The gas refrigerant is liquefied by the heat exchange with the cold outside air and the condensed liquid refrigerant is recovered in the receiver 204 via the condenser 203 of the evaporation / condensation heat exchanger A via the check valve 206 And then transferred to the liquid pump 200 to be continuously circulated.

The cold season operation mode shown in FIG. 2 includes a liquid pump 200, a separable heat pipe evaporator 201, a three-way electromagnetic valve 202, a separable heat pipe condenser 205, a check valve 206 ), A condenser 203 of the evaporation / condensation heat exchanger (A), and a receiver 204 are connected to each other through piping in sequence.

A separate type heat pipe condensing unit 205, which is a separate type heat pipe heat exchanger, is installed inside or outside the body of the thermo-hygrostat unit 1 so that heat exchange can be carried out with the cold provided by the cold outside air and the three- In the winter season, the refrigerator cooling circuit 10 is stopped, and the gas refrigerant circulating to the separable heat pipe condensing unit 205 is condensed using the cold air of the outside air and circulated to the separable heat pipe evaporator 201, Keep air at set temperature.

When the outside air temperature is low as in the winter season, by setting the flow of the three-way electromagnetic valve 202 to the separate heat pipe condenser 205 under the control of the outside air temperature sensor D, the refrigerant supplied to the separate heat pump condenser 205 The condensed liquid refrigerant passes through the check valve 206 and passes through the condensing section 203 of the evaporation / condensation heat exchanger A constituting the refrigerator cooling circuit 10 And then returns to the receiver (204).

Thus, in the winter season, the refrigerator cooling circuit 10 is shut off and the heat pipe cooling circuit 30 is operated to maintain the room temperature at the set temperature.

3 is a schematic view showing a summer operation mode of a constant temperature and humidity chamber equipped with a separate type heat pipe heat exchanger. In the summer, the refrigerator cooling circuit (10) and the heat pipe evaporation sub-circuit (20) are operated.

That is, in the summer, the operation of the separable heat pipe condenser 205 is cut off, and the refrigerator cooling circuit 10 and the separated heat pipe evaporator 201 are operated.

3, the refrigerant compressed at the high temperature and high pressure in the compressor 100 is condensed in the condenser 101,

The refrigerant supplied from the condenser 101 through the expansion valve 102 is lowered in pressure and temperature simultaneously with expansion due to heat exchange in the evaporator 103 of the evaporator / condenser heat exchanger A, To a continuous circulation,

The gas refrigerant supplied to the condenser 203 of the evaporation / condensation heat exchanger (A), which is in heat exchange with the condensed refrigerant supplied to the evaporator (103) of the evaporation / condensation heat exchanger (A) The refrigerant is collected by the receiver 204, is forcibly transferred to the detachable heat pipe evaporator 201 through the liquid pump 200,

The liquid refrigerant transferred to the detachable heat pipe evaporator 201 is evaporated to cool the room and the refrigerant changed into a gas is conveyed through the three-way electromagnetic valve 202 to the condenser 203 of the evaporator / condenser heat exchanger A Exchanges heat with the condensed refrigerant supplied to the evaporation portion 103 of the evaporation / condensation heat exchanger A, and then is conveyed to the receiver 204 for continuous circulation.

4 is a schematic diagram showing an intermediate season operating mode of a thermo-hygrostat equipped with a separate heat pipe heat exchanger.

The operation of the liquid pump 200 is controlled in accordance with the set temperature of the indoor temperature sensor C of the control unit 40 during the spring, autumn, or night, and according to the set temperature of the refrigerant temperature sensor B in the receiver 204, Controls the operation of the refrigerator cooling circuit (10), and controls the operation of the heat pipe cooling circuit (30) according to the set temperature of the outdoor temperature sensor (D).

Then, the control unit 40 synthesizes the signals transmitted from the respective temperature sensors and sequentially operates them individually or simultaneously.

4, the refrigerant compressed at the high temperature and high pressure in the compressor 100 is condensed in the condenser 101,

The refrigerant supplied from the condenser 101 through the expansion valve 102 is lowered in pressure and temperature simultaneously with expansion due to heat exchange in the evaporator 103 of the evaporator / condenser heat exchanger A, To a continuous circulation,

The gas refrigerant supplied to the condenser 203 of the evaporation / condensation heat exchanger (A), which is in heat exchange with the condensed refrigerant supplied to the evaporator (103) of the evaporation / condensation heat exchanger (A) The refrigerant is collected by the receiver 204, is forcibly transferred to the detachable heat pipe evaporator 201 through the liquid pump 200,

The liquid refrigerant transferred to the detachable heat pipe evaporator 201 is evaporated to cool the room and the refrigerant changed into a gas is transferred to the separable heat pipe condenser 205 through the three-way electromagnetic valve 202, The liquid refrigerant condensed by the heat exchange with the outside air is supplied to the condensing section 203 of the evaporation / condensation heat exchanger A via the check valve 206 to be supplied to the evaporation / condensation heat exchanger Exchanges heat with the condensed refrigerant supplied to the compressor (103), and then is conveyed to the receiver (204).

The constant temperature and humidity unit of the present invention eliminates the occurrence of the passage closure in the heat pipe by the refrigerant gas or the refrigerant liquid by applying the liquid pump circulation system, thereby improving the heat transfer efficiency and the heat exchange capacity.

For this reason, even when the heat transfer efficiency of the heat pipe is superior and the temperature difference between the indoor and the outdoor is relatively low, such as mid season, the heat pipe cooling circuit can easily use cold air, The cost can be reduced as much as possible.

To summarize the above control method of the thermo-hygrostat,

In the summer season, the refrigerator cooling circuit and the heat pipe evaporation sub-circuit 20 operate according to changes in the outside air temperature,

In the winter, only the heat pipe cooling circuit 30 is operated,

In the middle season, the refrigerator cooling circuit 10 or the heat pipe cooling circuit 30 is operated singly or in combination.

If the temperature of the outside temperature sensor (D) is 2 ~ 3 ℃ lower than the room temperature,

The direction of the gas refrigerant is directed to the separable heat pipe condensing section 205 by the three-way electromagnetic valve 202 so that the gas refrigerant in the separable heat pipe condensing section 205 is subjected to heat exchange and condensation process with the cold outside air do.

Such an operation mode is a winter mode and an intermediate season operation mode shown in Figs. 2 and 4, in which the cold air is sufficiently utilized, the liquid pump 200 is operated by the set temperature of the indoor temperature sensor, The liquid refrigerant is supplied to the evaporator 201 to cool the room. At this time, it is assumed that the set temperature of the room temperature sensor C is 26 [deg.] C as a specific example,

And controls the operation of the freezer according to the set temperature of the liquid refrigerant temperature sensor (B) in the receiver (204). At this time, it is preferable that the set temperature of the liquid refrigerant temperature reduction (B) is lower by 2 to 3 ° C than the room temperature.

In the middle season such as spring and autumn in the winter season, the direction of the three-way electromagnetic valve 202 is opened to the separable heat pipe condenser 205 by the control of the outside air temperature sensor D to perform heat exchange with the cold outside air.

However, when the indoor / outdoor temperature difference is not large, since the heat exchange of the separable heat pipe condensing part 205 is insufficient, the cooling ability of the refrigerant mixed with the gas is insufficient and at the same time, So that the freezer cooling circuit 10 is operated.

As a result, the refrigerant in which the gas is mixed is completely liquefied and the room is cooled stably.

In addition, the conventional refrigerator cooling circuit operation and reheating device and humidifying device of the conventional thermo-hygrostat are generally well-known technologies, and a description thereof will be omitted here.

Next, the refrigerant used in the thermo-hygrostat of the present invention will be further described.

Refrigerant is a generic term for a substance that performs a cooling function in a broad sense. It circulates in the cycle of a refrigeration system, a heat pump, an air conditioner, and a system utilizing heat energy, evaporates at a low temperature portion (evaporator), absorbs heat from a surrounding portion, Or a heat medium that emits heat in the heat medium. The purpose of such a refrigerant is to perform a phase change repeatedly in a liquid and a gaseous state.

HFCF22 has been used almost exclusively in domestic air conditioners and the market size is also the largest among all refrigerants. However, there is a problem with the problem of the ozone layer collapse and global warming.

In the present invention, a mixed refrigerant of HFC 32 and HFC125 is used as the alternative refrigerant of the HFCF22. More specifically, a mixed refrigerant composed of 10 to 60 wt% of difluoromethane (HFC32) and 40 to 90 wt% of pentafluoroethane (HFC125) is used.

The mixed refrigerant is an alternative refrigerant for HCFC22, which is advantageous in terms of energy efficiency compared to HCFC22.

In the summer, only the refrigerator cooling circuit is operated as in the conventional thermo-hygrostat, while the operation of the heat pipe cooling circuit is blocked. In the winter, the operation of the refrigerator cooling circuit is stopped and the cold refrigerant is used to cool the gas refrigerant to the heat pipe condenser So that the room air can be maintained at a desired temperature by circulating it through the liquid pump. In spring, autumn or night, the refrigerator cooling circuit and the heat pipe cooling circuit can be operated in an alternating manner to maintain the indoor environment at a desired temperature. This is a useful invention for the current century, which can reduce the operating time of the refrigerator cooling circuit, which consumes a lot of power in the operation of the hygrostat, thereby restricting energy consumption and serious problem of carbon emission rights.
