In general, a device for cooling a room and a device for heating are generally configured separately, but recently, a device for cooling a room in summer and a room for heating in winter has been developed. A typical example is an air heat heat pump type air conditioner using air heat as a heat source.

Here, the compressor 10 serves to generate a circulating pressure for refrigerant circulation by compressing and discharging the refrigerant at a high pressure. The compressor 10 may include a compressor as well as a compressor having a known configuration such as a reciprocating compressor, a rotary compressor, and a scroll compressor. Any compressor of any construction that allows compression is applicable.

An air conditioner 20 is connected to the compressor 10. The air conditioner 20 heats a room through heat exchange with cold indoor air while the high temperature refrigerant discharged from the compressor 10 flows through the winter, The low-temperature refrigerant passing through the condenser 30 and the cooling expansion valve 90 flows through and serves to cool the room through heat exchange with hot indoor air.

The air conditioner 20 may have a configuration of a general air conditioner, but as shown in FIG. 3, a case 21, an intake grill 22 installed above the front of the case 21, and a case 21. Exhaust grill 23 which is installed on the upper side of the front surface and directly connected under the intake grill 22, the indoor heat exchanger 24 installed on the inner lower side of the case 21, and the case 21. And a fan 25 for generating suction force to suck the indoor air through the intake grill 22 and to discharge it to the exhaust grill 23, and to downwardly switch the indoor air sucked through the intake grill 22.

Due to the configuration of the indoor heat exchanger 24 of the air conditioner 20 described above, the refrigerant does not flow through the second tubular heat exchanger 24b during the heating, but flows only through the first tubular heat exchanger 24a to the condenser 30. As provided, for example, when the refrigerant flow rates of the first and second tubular heat exchangers 24a and 24b are formed to be 7: 3, 70% of the heating load is exhausted in the air conditioner 20 and the remaining 30% of the heating load is provided. The evaporator 60 is exhausted through heat exchange with the cooling load in the condenser 30, such as providing heat for refrigerant evaporation.

Here, the evaporator 60 flows through the condenser 30, which means that the evaporator 60 is arranged along the inside of the condenser 30, which is actually an outdoor side heat exchanger, that is, a double pipe in which the condenser 30 surrounds the evaporator 60. In addition to having a configuration of the evaporator 60 includes adjacent to the condenser 30 is arranged in the same shape.

In the case of), the heat for refrigerant evaporation can be supplied from the condenser 30 so that a part of the heating load of the air conditioner 20 is exhausted with the cooling load in the condenser 30 so as to exhaust the cooling load. do.

Heat pump type air-conditioning device 1 according to the present invention described above preferably comprises a four-way valve 70 provided between the compressor 10 and the air conditioner 20, this four-way valve 70 is heating At this time, the high temperature and high pressure refrigerant discharged from the compressor 10 is provided to the air conditioner 20, and at the same time, the flow path is set so that the refrigerant flowing through the evaporator 60 is provided to the compressor 10 again. The high temperature and high pressure refrigerant discharged from 10) is provided to the evaporator 60, and at the same time, the flow path is set so that the refrigerant flowing through the air conditioner 20 is provided to the compressor 10 again.

In addition, the heat pump type air conditioner (1) according to the present invention described above is connected to the evaporator (60) to complete the cooling cycle, the cooling dryer (80) for drying the refrigerant discharged from the evaporator (60) during cooling ), A cooling expansion valve (90) connected to the cooling dryer (80) and expanding the refrigerant discharged from the cooling dryer (80) during cooling to provide to the air conditioner (20); It is preferable that the expansion valve 90 further comprises a cooling connection pipe line 100 for branching the air conditioner 20.

And check valves 105 and 107 for allowing the flow direction in only one direction.

In addition, the heat pump type air conditioner (1) according to the present invention described above is provided in the conduit between the evaporator 60 and the four-way valve 70 to operate a more efficient heating cycle for the operation as a heating expansion valve (50) It is preferable to further include a first temperature sensor 110 for providing a control signal, in this case, the heating expansion valve 50 is introduced into the refrigerant, that is, the compressor 10 is detected by the first temperature sensor 110. When the temperature of the refrigerant is lower than the set temperature, that is, when the cooling load remains, the expansion valve flows through itself to reduce the amount of expanded refrigerant or to reduce the amount of expansion of the refrigerant. It is preferable that it consists of.

In addition, the heat pump type air conditioner 1 according to the present invention is provided in the conduit between the four-way valve 70 and the compressor 10 so that a more efficient cooling cycle can be made to operate as an expansion valve 90 for cooling. It is preferable to further comprise a second temperature sensor 120 for providing a control signal for this, in this case the cooling expansion valve 90 is a refrigerant sensed by the second temperature sensor 120, that is, the compressor 10 When the temperature of the refrigerant flowing into is higher than the set temperature, that is, when the heating load remains, it flows through itself so as to increase the amount of the expanded refrigerant or to increase the degree of expansion of the refrigerant. It is preferably composed of an electronic expansion valve.

In addition, the heat pump type heating and cooling device 1 according to the present invention, the heating bypass is branched to the front and rear of the third temperature sensor 130 and the heating expansion valve 50 provided in the compressor 10. The capillary tube 150, which is provided on the heating bypass pipe line 140, expands the refrigerant flowing through the inside of the heating pipe, and is installed in front of the capillary pipe 150 on the heating bypass pipe path 140. And further includes a heating control servovalve 160 that is closed when the outside temperature by the third temperature sensor 130 is less than or equal to the set temperature.

When the outside air temperature detected by the third temperature sensor 130 is higher than the set temperature during the winter heating by the above-described configuration, the heating control servovalve 160 for opening and closing the heating bypass pipe 140 is opened for heating. While the refrigerant discharged from the dryer 40 is expanded through the heating expansion valve 50 and the capillary tube 150, when the outside air temperature detected by the third temperature sensor 130 is lower than or equal to the set temperature, the heating bypass pipe line ( As the servo valve 160 for opening and closing the heating and closing 140 is closed, the refrigerant discharged from the heating dryer 40 may be expanded only through the expansion valve 50 for heating, and thus the amount of refrigerant flowing into the evaporator 60 may be controlled. Will be.

In addition, the heat pump type air-conditioning apparatus 1 according to the present invention described above preferably further comprises an accumulator 170 provided between the compressor 10 and the four-way valve 70, the accumulator 170 is By accumulating the refrigerant discharged from the compressor 10 and providing the required amount of refrigerant to the four-way valve 70, the overall refrigerant flow is uniformly regulated.

Hereinafter, with reference to the accompanying drawings, the overall operation of the heat pump type heating and cooling device according to the present invention will be described as follows:

In the heating of the winter season, as shown in FIG. 1, the high temperature and high pressure refrigerant discharged from the compressor 10 passes through the accumulator 170 and the four-way valve 70 to form the first tubular heat exchanger 24a of the air conditioner 20. An evaporator that heats the room through heat exchange with indoor air while passing through the bay, flows into the condenser 30, condenses, expands the expansion valve 50 for heating, and then flows through the condenser 30 through the heating dryer 40. After evaporating through (60), it is repeated to flow back into the compressor (10) via the four-way valve (70).

In this case, the refrigerant cannot flow through the second tubular heat exchanger 24b of the indoor heat exchanger 24 of the air conditioner 20, but flows through only the first tubular heat exchanger 24a to the condenser 30. For example, when the flow rate of the refrigerant of the first and second tubular heat exchangers 24a and 24b is 7: 3, 70% of the heating load is exhausted in the air conditioner 20, and the evaporator 60 flows through the condenser 30. As a result, the remaining 30% of the heating load exhausts the cooling load as the heat exchanger with the cooling load in the condenser 30 provides heat for evaporation of the refrigerant to the evaporator 60.

Usually, when the part of the heating load is exhausted in the condenser 30 corresponding to the outdoor unit, the heating efficiency may be deteriorated. However, the part of the heating load is not simply discarded in the condenser 30 corresponding to the outdoor unit. As the heat exchanger consumes all of the cooling load, the heating efficiency is drastically reduced, and the overall efficiency is increased by solving all the problems caused by the drop in the outside temperature such as dropping due to the remaining cooling load.

In addition, in the case of the heating expansion valve 50, when the temperature of the refrigerant sensed by the first temperature sensor 110, ie, the temperature of the refrigerant flowing into the compressor 10, becomes lower than the set temperature due to the remaining of the cooling load. It is possible to further increase the heating efficiency as it is controlled in a direction to reduce the amount of the expanded refrigerant by flowing through itself or to reduce the degree of expansion of the refrigerant.

In addition, when the outside air temperature detected by the third temperature sensor 130 is higher than the set temperature, the heating control servovalve 160 which opens and closes the heating bypass pipe 140 is opened and is discharged from the heating dryer 40. While the refrigerant is expanded through the heating expansion valve 50 and the capillary tube 150, when the outside air temperature detected by the third temperature sensor 130 is less than the set temperature for heating control for opening and closing the heating bypass pipe 140 As the servo valve 160 is closed, the refrigerant discharged from the heating dryer 40 can be expanded only through the expansion valve 50 for heating, so that the amount of refrigerant flowing into the evaporator 60 can be controlled, thereby reducing the external air temperature. It can be solved as much as possible.

During the summer cooling, as shown in FIG. 2, the high temperature and high pressure refrigerant discharged from the compressor 10 flows into the evaporator 60 through the accumulator 170 and the four-way valve 70, and then heat exchanges with external air. After condensation by the air-cooling dryer 80 through the expansion expansion valve 90 for cooling and then the first and second tubular heat exchanger (24a and 24b) of the air conditioner 20 while the heat exchange with the indoor air After cooling the room through the four-way valve 70 it is repeated to flow back into the compressor (10). In this case, as in the normal cooling cycle, the refrigerant passes through both the first and second tubular heat exchangers 24a and 24b of the air conditioner 20 such that 100% of the cooling load of the air conditioner 20 is exhausted to the condensation load. do.
