Problems solved by technology

[0002] The two invention patents with application numbers of 200710162570.0 and 200710305376.3 are both related to a winter and summer dual-purpose heat pump device. In this device, if the condensation temperature of the refrigerant is too high or the evaporation temperature is too low, the throttle valve will throttle The increase in loss will lead to an increase in the gas content in the gas-liquid two-phase mixture after throttling, so that the heat exchange capacity of the evaporator cannot be fully utilized, thereby reducing the efficiency of the heat pump device. On the other hand, it will cause the compressor exhaust temperature to be too high. In severe cases, it will affect the normal operation of the compressor

Embodiment 1

[0029] like figure 1 As shown, the whole device includes the following equipment: scroll compressor 1, heat source side heat exchanger 2, user side heat exchanger 3, second heat exchanger 6, first throttling mechanism 4, second throttling mechanism 5, The first four-way valve 100, the second four-way valve 70, the first flow control valve 7-1, the second flow control valve 7-2, the third throttling mechanism 8, the economizer 11, the first one-way valve 51, The second one-way valve 52, the third one-way valve 95, the fourth one-way valve 96, the fifth one-way valve 97, the sixth one-way valve 98, the first three-way valve 12 and the second three-way valve 13.

[0030] The first four-way valve 100 is provided with four connection nodes: 101, 102, 103, 104; the second four-way valve 70 is also provided with four connection nodes 71, 72, 73, 74; channels are connected.

[0031] The heat source side heat exchanger 2 and the user side heat exchanger 3 are refrigerant-air heat exc...

Embodiment 2

[0072] figure 2 As shown, compared with Embodiment 1, there are two differences: 1) replace the third one-way valve 95 with the third flow control valve 7-3; 2) the position of the second three-way valve 13 in the system The positions are different. In this embodiment, the normally open node A3 of the second three-way valve 13 is connected to the heat source side heat exchanger 2 through the forty-ninth pipeline 49, and one of the two reversing nodes of the second three-way valve 13 B3 is connected to the connection node 72 of the second four-way valve 70 through the thirty-first pipeline 31, and another reversing node C3 of the second three-way valve 13 is connected to the second heat exchanger 6 and the third flow direction control valve 7- 3 and the pipeline between the outlet of the fourth one-way valve 96 is connected. The other equipment and connection methods in the device are the same as those in Embodiment 1.

[0073] Embodiment 2 has exactly the same function as E...

Embodiment 3

[0104] image 3 As shown, it also has the function described in Embodiment 1, the only difference is that the second three-way valve 13 is replaced by the third four-way valve 80. Its working process is as follows:

[0105] (1) Simple cooling in summer

[0106] When working, the first throttling mechanism 4 and the third throttling mechanism 8 work normally, the second throttling mechanism 5 is fully open, the first flow control valve 7-1 and the second flow control valve 7-2 are closed, the first three The normally open node A1 of the through valve 12 communicates with the reversing node C1.

[0107] During operation, the low-temperature and low-pressure refrigerant vapor enters the scroll compressor 1 through the sixty-third pipeline 63 and is compressed into superheated vapor of the high-temperature and high-pressure refrigerant. , 104, the sixty-first pipeline 61, the second four-way valve 70 connecting nodes 71, 72, the thirty-first pipeline 31, the third four-way valve...

Abstract

The invention discloses a multifunctional air-conditioning heat pump device, which includes a compressor, a heat source side heat exchanger, a user side heat exchanger, a second heat exchanger, a first throttling mechanism, a second throttling mechanism, a first four-way valve, the second four-way valve, the first flow control valve and the second flow control valve; it also includes an economizer, a third throttling mechanism, a first one-way valve, a second one-way valve, a third one-way valve, The fourth one-way valve, the fifth one-way valve, the sixth one-way valve, the first three-way valve and the second three-way valve; during operation, the economizer is used to make the refrigerant liquid before throttling be supercooled. The refrigerant gas generated by the economizer supplies air for the compressor, so the multifunctional air-conditioning heat pump device can work normally in high and low temperature working environments, and realize various operating conditions such as production of domestic hot water, cooling or heating, etc., with a simple structure, It is reliable in work and low in cost, and is especially suitable for small and medium-sized civilian occasions that require domestic hot water.

Description

technical field [0001] The invention relates to a multifunctional air-conditioning heat pump device, which belongs to the technical field of air-conditioning and refrigeration. Background technique [0002] The two invention patents with application numbers of 200710162570.0 and 200710305376.3 are both related to a dual-purpose heat pump device for winter and summer. In this device, if the condensation temperature of the refrigerant is too high or the evaporation temperature is too low, the throttle valve will throttle The increase in loss will lead to an increase in the gas content in the gas-liquid two-phase mixture after throttling, so that the heat exchange capacity of the evaporator cannot be fully utilized, thereby reducing the efficiency of the heat pump device. On the other hand, it will cause the compressor exhaust temperature to be too high. In severe cases, it will affect the normal operation of the compressor.
