Description

A thermohygrostat of one body type

The present invention relates to an integrated thermo-hygrostat, comprising a heat exchanger for supercooling the cooling water to be condensed in the condenser, and to an integrated thermo-hygrostat that can increase the condensation efficiency of the hot summer condenser by cooling the supercooled water by the heat exchanger to the condenser. will be.

In Applicant's patent application No. 2001-35851 (filed June 22, 2001), an integrated thermo-hygrostat is introduced. However, the integrated thermo-hygrostat has a disadvantage in that a receiver is disposed between the condenser and the expansion valve so that refrigerant gas not condensed in the condenser is introduced into the expansion valve, thereby degrading the operation efficiency of the expansion valve.

Accordingly, an object of the present invention is to provide an integrated thermo-hygrostat that can increase the condensation efficiency of a hot summer condenser by arranging a heat exchanger for supercooling the cooling water sprayed on the condenser, and the cooling water supercooled by the heat exchanger is sprayed into the condenser.

Preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings.

Referring to FIG. 1, the integrated thermo-hygrostat according to the present invention is divided into an outdoor part 5 and an indoor part 7 by a vertical bulkhead 3, and compresses a refrigerant to the outdoor part 5. And a condenser 13 for condensing the refrigerant in a gaseous state compressed by the compressor 11, and an air filter 21 for filtering outside air introduced into the indoor unit 7 into the indoor unit 5. The first expansion valve 23 for isotropically expanding the high temperature and high pressure refrigerant discharged from the condenser 13, the evaporator 25 for evaporating the refrigerant discharged from the first expansion valve 23, the room heating Heater 27, humidifier 29 for indoor humidification, outdoor air intake damper 31 used to lower the temperature of the interior of the building in winter, and cold or warmth and humidity of the interior part 7 into the building The blowing fan 33 which discharges is arrange | positioned.

In addition, the integrated thermo-hygrostat according to the present invention has a second line (L2) branched from the first line (L1) connecting the condenser (13) and the first expansion valve (23), the second line (L2) The second solenoid valve V1, the second expansion valve 41, and the heat exchanger 43 are connected in series, and the temperature sensor 45 is mounted on the heat exchanger 43, and is supplied to the cooling water line L3. The cooling water to be cooled and the low-temperature gas refrigerant passing through the second expansion valve 41 are heat-exchanged in the heat exchanger 43, whereby the cooling water sprayed by the condenser 13 is supercooled to a low temperature.

Like the first expansion valve 23, the second expansion valve 41 phase-changes a high temperature liquid refrigerant into a low temperature gas refrigerant. In addition, as shown in FIG. 2, a capillary tube 47 may be disposed between the second solenoid valve V2 and the heat exchanger 43 instead of the second expansion valve 41.

Reference numeral V3, which has not been described, is a third solenoid valve, and a temperature sensor (not shown) is mounted on the outdoor unit 5 including the condenser 13 so that the temperature measured by the temperature sensor is controlled. If the set value is greater than or equal to the set value, the third solenoid valve V3 may be automatically operated, or the user may arbitrarily control the opening and closing operation.

For example, when the temperature sensor 45 measures the temperature of the cooling water supplied to the heat exchanger 43 and the temperature of the cooling water is 15 ° C. or more, the second solenoid valve V2 is opened to allow the refrigerant to expand into the second expansion valve. When the temperature of the cooling water is less than 15 ° C., the second electric valve V2 is closed to prevent the refrigerant from being supplied to the heat exchanger 43 via the 41.

The operation of the integrated thermo-hygrostat according to the present invention configured as described above will be described by way of example.

Since the air-cooled condenser 13 is greatly influenced by the external temperature, when the temperature of the outdoor unit 5 is high due to the high external temperature in summer, the operating efficiency of the condenser 13 is reduced. In order to prevent this, the present invention is to spray the cooling water supercooled by the air-cooled condenser 13 through the sprinkler 51 to lower the external temperature of the condenser 13, thereby increasing the condensation efficiency of the condenser 13.

That is, when the refrigerant condensed in the condenser 13 is supplied to the first expansion valve 23 through the first line L1, the temperature of the refrigerant is approximately 30 ° C. to 35 ° C., and the first line L1. When a portion of the liquid refrigerant flowing through) is bypassed to the second line L2 and passes through the second expansion valve 41, the refrigerant is low temperature (approximately 0 to 5 ° C.) by the second expansion valve 41. Is phase-converted to the gas refrigerant of. In this way, the low-temperature gas refrigerant is supplied to the heat exchanger 43 and heat-exchanged with cooling water of about 15 ° C. to 18 ° C. in summer, and thus the cooling water is supercooled to 5 ° C. to 10 ° C.

Thereafter, the heat-exchanged refrigerant is joined to the refrigerant of the third line (L4) connecting the evaporator 25 and the compressor 11, and the supercooled cooling water is sprinkled by the condenser 13. The sprinkling water sprinkler 51 may be a nozzle or a sprinkler for spraying generally known water. The configuration of the nozzle and the sprinkler is already well known and detailed description thereof will be omitted.

As described above, the integrated thermo-hygrostat according to the present invention can increase the condensation efficiency of the condenser in the hot summer by spraying the coolant supercooled by the heat exchanger, thereby increasing the cooling efficiency.
