Problems solved by technology

[0002] Heat pump is a common refrigeration equipment. When the heat pump is in the heating mode, the outdoor heat exchanger is seriously frosted and needs to be shut down frequently to defrost. On the one hand, it increases energy consumption, and on the other hand, it affects the heat transfer performance of the unit.

Abstract

The invention discloses a novel solution defrosting and refrigeration regenerative heat pump device. The novel solution defrosting and refrigeration regenerative heat pump device comprises a compressor. An outlet of the compressor passes through a four-way reversing valve, a plate heat exchanger, a dryer, a first heating power expansion valve, a refrigeration regenerative heat exchanger, a second heating power expansion valve and a finned tube exchanger, and then passes through the four-way reversing valve and a gas-liquid separator to return to an inlet of the compressor. A solution catch tray is arranged below the refrigeration regenerative heat exchanger. The solution catch tray sprays a solution in the solution catch tray onto the refrigeration regenerative heat exchanger through a solution pump. The novel solution defrosting and refrigeration regenerative heat pump device has the advantages that halting of the heat pump unit during defrosting period can be avoided, no extra energy consumption is added in the defrosting process, frosting and defrosting loss coefficients of the air cooled heat pump unit can be better increased, and heat making performance of the heat pump unit is improved.

Description

technical field [0001] The invention relates to a heat pump, more precisely, a novel solution defrosting and freezing regeneration heat pump device. Background technique [0002] Heat pump is a common refrigeration equipment. When the heat pump is in the heating mode, the outdoor heat exchanger is severely frosted and needs to be shut down frequently for defrosting. On the one hand, it increases energy consumption, and on the other hand, it affects the heat exchange performance of the unit. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a novel solution defrosting and freezing regeneration heat pump device. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A novel solution defrosting and freezing regeneration heat pump device, the novel solution defrosting and freezing regeneration heat pump device includes a compre...
