Embodiment Construction

[0018] Specific embodiments of the present invention are described below in conjunction with accompanying drawing:

[0019] Please refer to Figure 1, which is a schematic diagram of the structural connection of a water heat exchanger in an air source heat pump system. It can be seen from the figure that one end of the water heat exchanger 5 is connected with the reversing valves 3 and 4, and the other end is connected with the reversing valves 3 and 4. The throttling valves 6 and 7 are connected, and the inside of the water heat exchanger 5 is provided with a refrigerant channel; the internal refrigerant channel of the water heat exchanger is set as a dual channel 51 and 52 that are independent of each other, and share a water system; the channel 51 One end of the channel 52 is correspondingly connected to a corresponding throttle valve 6 and a reversing valve 3; one end of the channel 52 is correspondingly connected to a corresponding throttle valve 7 and a reversing valve 4; ...

Abstract

The invention discloses a water heat exchanger for an air-source heat pump system with one end connected with a reversing valve and the other end connected with a throttling valve. A refrigerant passage is provided inside the water heat exchanger, and has independent dual passages that share a water system; one end of the each passage is respectively connected with the corresponding throttling valve and the corresponding reversing valve; and when one passage of the water heat exchanger is at evaporation state, the other passage is at condensation state. In the water heat exchanger for the air-source heat pump system, the water heat exchanger adopts dual-passage design, so that the two passages of heat exchangers with different functions can perform energy exchange through sharing the conductive medium (water) when the system performs reversing defrosting, and the refrigerant in the air-source heat pump system can be not subjected to acute transfer and acute pressure and temperature changes, so as to solve the unreliable problem of the air-source heat pump system during defrosting process.

Description

technical field [0001] The invention relates to a water heat exchanger, in particular to a water heat exchanger for an air source heat pump system, belonging to an air conditioning system. Background technique [0002] The air source heat pump system, also known as the air source central air conditioning system, is a heat pump type integrated air conditioning device that uses air as the heat source and can perform refrigeration / heating cycles. Air is the source of heat rejection. Air is used as the cold source / heat source carrier, without cooling towers, cooling pumps and cooling pipelines, which can save a lot of valuable water or land resources, and also avoid pollution of water quality; the air source heat pump system is placed outdoors and does not occupy indoor buildings Space, save the special refrigeration room and boiler room, reduce civil engineering investment; when the system is running, no "waste residue, waste gas, waste liquid" is generated, which is an enviro...
