In the dehumidification heater 20, the dehumidification heating cycle 40 may provide a second condenser 420 and a condenser 42 in series in the refrigerant circulation line 45 as shown in FIG. In this case, since there is no need to switch the flow of the refrigerant to the condenser 42 or the second condenser 420, the switching valve 47 is not necessary.

The dehumidifying heating apparatus capable of recovering excess heat of the house according to the present invention configured as described above operates the dehumidifying heating cycle 40 installed in the house 10, but the operation mode is selected and operated according to the conditions in the house 10. do.

In other words, if the house temperature is 20 ~ 30 ℃ and the humidity is 65% or higher, the dehumidification mode is selected and operated. In the evening, the house temperature is 5 ~ 15 ℃ and the humidity is 65%. In case of low temperature and high humidity, the heating mode is selectively operated.

First, when selected and operated in the dehumidification mode, as shown in FIG. 3, the refrigerant passing through the compressor 41 by the four-way valve 46 and the switching valve 47 passes through the expansion valve 43 through the second condenser 420. It is switched to circulate to the evaporator 44 and the compressor 41. When the dehumidification heating cycle 40 is operated while the four-way valve 46 and the switching valve 47 are switched as described above, the compressor 41 is operated to be compressed into a high-temperature, high-pressure gas refrigerant. The liquid is compressed into the condenser 420 and condensed into a liquid refrigerant having a high temperature and high pressure while being heated and heated around the second condenser 420 while the refrigerant is passed through the second condenser 420.

The liquid refrigerant of the high temperature and high pressure condensed in this way is transformed into a low pressure state in the expansion valve 43 to be evaporated in the evaporator 44. Thus, as the refrigerant evaporates (evaporates) in the evaporator 44, the heat of vaporization of the refrigerant required for vaporization is evaporated. Absorption from the outside causes the surroundings of the evaporator 44 to be cooled and dehumidified.

The low-temperature, low-pressure gas refrigerant passing through the evaporator 44 is compressed by suction by the compressor 41 to allow continuous heat exchange in the evaporator 44 while repeatedly performing the aforementioned process.

Thus, while the dehumidification heating cycle 40 of the dehumidifying heater 20 is operated, the airflow flow fan 55 in the branch induction pipe 50 is also operated, so that the temperature is 20 to 30 through the inlet 31 of the enclosure 30. Air in the house 10 having a temperature of 65 ° C. and higher than 65 ° C. is introduced into the house 10 through the outlet 32 and the branch induction pipe 50 of the housing 30.

At this time, the evaporator 44 of the dehumidification heating cycle 40 absorbs the heat of vaporization of the refrigerant necessary for evaporation (vaporization) from the air in the evaporator 44, so that the surroundings of the evaporator 44 are cooled.

Therefore, while passing through the evaporator 44 provided in the inlet 31 of the housing 30, the air is about 10 ℃, due to which the moisture in the air is mostly condensed to form a drop of water (condensed water) to fall to the lower absolute humidity It is to dehumidify.

The dehumidified air is moved to the condenser 42 on the outlet 32 side where the refrigerant of the dehumidification heating cycle 40 does not flow, and then is discharged along the branch induction pipe 50 connected to the outlet 32, and then branch induction. It is not heated because it is ejected through the branch hole 51 of the pipe 50.

As this is dehumidified as the air of about 10 ℃ is supplied to the house 10 inside the house 10, the crop or fruit to be stored or cultivated can be kept at a suitable temperature as well as humidity to grow.

At the same time, since the recovery pump 62 on the recovery flow path 61 is operated, the heat medium in the recovery tank 60 is sucked and the recovery tank 60 passes through the recovery flow path 61, the second condenser 420, and the recovery flow path 61. The process of returning to) continues.

Therefore, in the second condenser 420, the heat medium absorbs the condensation heat of the refrigerant by the water heat exchange method, and thus is heated to about 50 ° C., and thus the heated heat medium is stored in the recovery tank 60. It can recover and store the excess heat that air has.

As described above, when the temperature of the house drops to 15 ° C. or lower while using the dehumidifying mode, the dehumidifying heater 20 is operated in the heating mode. When the heating mode is selected and operated as shown in FIG. 4, the refrigerant passing through the compressor 41 by the four-way valve 46 and the switching valve 47 passes through the expansion valve 43 and the evaporator 44 through the condenser 42. ) And the compressor 41 to be circulated. When the dehumidification heating cycle 40 is operated while the four-way valve 46 and the switching valve 47 are switched in this way, the compressor 41 is operated to be compressed into a high-temperature, high-pressure gas refrigerant, and the compressed refrigerant is condenser ( 42, and the refrigerant is heat exchanged (heated) while passing through the condenser 42 to condense into a liquid refrigerant having a high temperature and high pressure while warming around the condenser 42.

The high temperature and high pressure liquid refrigerant condensed in this way is transformed into a low pressure state in the expansion valve 43 to be evaporated in the evaporator 44. Thus, the evaporator 44 absorbs the heat of vaporization of the refrigerant required for evaporation (evaporation) from the outside. Therefore, the circumference of the evaporator 44 is cooled and dehumidified.

The low-temperature, low-pressure gas refrigerant passing through the evaporator 44 is compressed by suction by the compressor 41 to allow continuous heat exchange in the evaporator 44 while repeatedly performing the aforementioned process.

The air in the house 10 having a temperature of 65 ° C. and higher than 65 ° C. is introduced to be discharged to the house 10 through the outlet 32 and the branch induction pipe 50 of the housing 30.

At this time, the evaporator 44 of the dehumidification heating cycle 40 constituting the dehumidifier heater 20 absorbs the vaporization heat of the refrigerant required for evaporation (vaporization) from the air in the evaporator 44, and thus the surroundings of the evaporator 44 are cooled. It is in a state. Therefore, while passing through the evaporator 44 provided in the inlet 31 of the enclosure 30, the air is about 0 ~ 10 ℃ and this is due to the condensation of water in the air is mostly condensed and falling to the bottom to lower the absolute humidity to dehumidify To do.

The dehumidified air is moved to the condenser 42 on the outlet 32 side, and the condenser 42 dissipates the heat of the high-temperature refrigerant therein and thus absorbs heat while passing through the condenser 42. Pass through with primary warming to ˜15 ° C.

At the same time, the heat dissipation pump 67 of the heat dissipation passage 66 is also operated, so that the heat medium in the recovery tank 60 which collects and stores the excess heat of the house 10 while operating the dehumidification heater 20 in the dehumidification mode during the day. The process of returning to the recovery tank 60 through the heat dissipation passage 66, the radiator 65, and the heat dissipation passage 66 is continuously performed, so that the heat medium of the recovery tank 60 is circulated.

The air warmed primarily to 5 to 15 ° C. by the condenser 42 of the dehumidification heating cycle 40 is secondly warmed to 10 to 20 ° C. while passing through a radiator 65 through which a heat medium of 50 ° C. flows. The air dehumidified and warmed through the first and second air is discharged along the branch induction pipe 50 and then ejected through the branch hole 51 of the branch induction pipe 50, so that the inside of the house 10 is dehumidified and heated. You lose.

Thus, since dehumidified and warmed air is supplied to the inside of the house 10, it is possible to maintain the humidity as well as the temperature suitable for growing crops or fruit trees stored or grown in the house 10.
