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 loss increases, resulting in an increase in the gas content in the refrigerant 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, and on the other hand, it will cause the compressor discharge temperature to increase. Too high, in severe cases, it will affect the normal operation of the compressor

Embodiment 1

[0036] Such as figure 1 As shown, the whole device includes the following equipment: 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, first throttling mechanism Four-way valve 100, second four-way valve 70, first flow control valve 7-1, second flow control valve 7-2, ninth flow control valve 7-9, flash device 9, third throttling mechanism 8 and a third flow direction control valve 7-3. The flash device 9 has four connection ports, including a flash device 50 with four nodes, and the four nodes of the flash device 50 are connected with the four connection ports of the flash device 9 respectively, and one connection port of the flash device 9 It is connected with the third flow direction control valve 7-3, the other connection port is connected with the sixty-eighth pipeline 68, and the other two connection ports are respectively connected with the forty-sixth pipel...

Embodiment 2

[0076] figure 2 As shown, compared with Embodiment 1, the only difference is that a three-way valve 10 is added. The normally open node A1 of the three-way valve 10 is connected to the heat source side heat exchanger 2 through the forty-eighth pipeline 48. The three-way One of the two reversing nodes B1 of the valve 10 is connected to the connection node 74 of the second four-way valve 70 through the forty-first pipeline 41, and the other reversing node C1 of the three-way valve 10 is connected to the second heat exchanger 6 and the third The forty-fifth pipeline 45 between the throttling mechanisms 8 is connected. And other equipment in the device and connection mode are exactly the same as embodiment 1; In the work, different from embodiment 1 is: in summer refrigeration simultaneously recovers condensation heat to produce domestic hot water cycle, flash evaporator 50 also works normally, separates flash Vapor body. The workflow of each working condition is as follows:

Embodiment 3

[0110] image 3 As shown, compared with Embodiment 2, the only difference is that the position of the three-way valve 10 in the system is different. In this embodiment, the normally open node A1 of the three-way valve 10 is connected to the second heat exchanger 6 through the forty-ninth pipeline 49, and B1, one of the two reversing nodes of the three-way valve 10, is connected to the second heat exchanger 6 through the forty-fifth pipeline 45 It is connected with the third throttling mechanism 8 , and another reversing node C1 of the three-way valve 10 is connected with the forty-first pipeline 41 between the heat source side heat exchanger 2 and the connection node 74 of the second four-way valve 70 . The other equipment and connection methods in the device are exactly the same as those in Embodiment 2. Embodiment 3 has exactly the same function as Embodiment 2.

Abstract

The invention disclose an air conditioning heat pump, which comprises a compressor, a heat exchanger at the side of a heat source, a heat exchanger at the side of a user, a second heat exchanger, a first throttle mechanism, a second throttle mechanism, a third throttle mechanism, a first four-way valve, a second four-way valve, a first flow controlling valve, a second flow controlling valve, a third flow controlling valve, a ninth flow controlling valve and a flash evaporator. In operation, the flash gas generated in the separating and throttling process of the flash evaporator is used for supplying air for the compressor, thus realizing normal operation under high and low temperature working conditions as well as meeting various production needs for domestic hot water, cooling and heating, and so on. With simple structure, reliable operation and low cost, the air conditioning heat pump is especially suitable for small and medium air conditioning heat pumps of civilian use and with a need for domestic hot water.

Description

technical field [0001] The invention relates to an air-conditioning heat pump device, which belongs to the technical field of refrigeration. Background technique [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 loss increases, resulting in an increase in the gas content in the refrigerant 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, and on the other hand, it will cause the compressor discharge temperature to increase. If it is too high, it will affect the normal operation of the compressor in severe cases. Contents of the invention [0003] The object of the prese...
