Embodiment Construction

[0013] The device of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] The arrow points to the refrigerant flow direction of the heat pump water heater. When the heat pump water heater is heating hot water, the compressor 1 starts to run. The refrigerant is from compressor 1 → hot water tank 2 → throttle valve 3 → waste cold recovery device 4 → outdoor condenser 5 → gas-liquid separator 6 → compressor 1. Since the waste cold recovery device 4 is arranged between the throttle valve 3 and the outdoor condenser 5 , the waste cold generated by the heat pump water heater is first recovered by the waste cold recovery device 4 . When the waste cold collection capacity of the waste cold recovery device 4 is exceeded, the excess waste cold can be discharged from the outdoor condenser 5 . Since the waste cold recovery device 4 is placed in the refrigerator or the air conditioner fan, the was...

Abstract

The invention discloses a refrigerant circulating device for recycling residual cool of a heat pump water heater. The refrigerant circulating device is composed of a compressor, a water tank heat exchanger, a throttle valve, a residual cool recycling device, an outdoor condenser and a gas and liquid separator. The residual cool recycling device is arranged between the throttle valve and the outdoor condenser and is arranged in an air conditioner fan or a refrigerator. The refrigerant circulating device is used for recycling residual cool of the heat pump water heater and is used as a cold source of the air conditioner fan or the refrigerator or a refrigerator and air conditioner fan all-in-one machine, and the effects of saving energy and protecting the environment are achieved.

Description

technical field [0001] The invention is applicable to a combined refrigerator-heat pump water heater integrated machine, or a combined air conditioner fan-heat pump water heater integrated machine and other HVAC products. Specifically, it relates to a refrigerant circulation device used for recovery of waste cold from heat pump water heaters. Background technique [0002] Most families, restaurants, and hotels need to use hot water all year round. If there are a considerable number of families and units, heat pump water heaters, especially air energy water heaters, are selected. These devices will generate a lot of residual cooling during the process of being transported for hot water for many years. Most of the heat pump water heaters are exhausted to the outside, resulting in a huge waste of cold energy. [0003] So far, products on the market have not yet seen the use of this refrigerant circulation device. Contents of the invention [0004] The purpose of the prese...
