Abstract

The invention discloses a liquid heat exchange type air source heat pump and relates to the technical field of air source heat pump systems. The liquid heat exchange type air source heat pump comprises a liquid heat source heat pump, a heat source liquid inlet pipeline, a heat source liquid return pipeline, an air liquid heat exchanger and a closed air channel. A heat exchange pipeline in the liquid heat source heat pump communicates with a heat exchange pipeline in the air liquid heat exchanger through the heat source liquid inlet pipeline and the heat source liquid return pipeline. A circulating pump is further arranged in the heat source liquid inlet pipeline or the heat source liquid return pipeline. The circulating pump drives heat exchange liquid to flow from the inside of the heat source liquid return pipeline to the liquid inflow end of the air liquid heat exchanger. An air pre-heat-exchange chamber is arranged at an air inlet of the closed air channel. One part of the heat source liquid return pipeline is arranged in the air pre-heat-exchange chamber. The air liquid heat exchanger is arranged on the non-air-pre-heat-exchange chamber part of the closed air channel. The problems of frosting and freezing of the heat pump and the cold island effect formed when the air source heat pump is arranged on a large scale are solved, large-area heat exchange can be achieved, the popularization degree is high, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of air source heat pump systems, in particular to a liquid heat exchange type air source heat pump. Background technique [0002] After years of development, the air source heat pump has become one of the mainstream products in the energy-saving field, with its performance improving day by day and its cost constantly decreasing. The air generally contains water vapor, and it is generally believed that the most likely condition for water vapor condensation to occur is when the ambient temperature is between 5°C and 0°C and there is fog or rain and snow. If water vapor condenses on the surface of the air heat exchanger, as the air temperature further decreases, the condensed water on the surface of the heat exchanger will start to frost and freeze, which will reduce the heat exchange efficiency of the heat exchanger and affect the overall performance of the machine. efficiency. Some data show that due to the...
