Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, in particular to an air source heat pump antifreeze device. Background Art

[0002] Air source heat pump is a green energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It is a type of heat pump technology that uses the energy in the air as the main power and drives the compressor through a small amount of electricity. It has multiple advantages such as low cost, easy operation, good heating effect, safety, cleanliness, green energy saving, etc. In actual use, if the air source heat pump suddenly loses power, the unit will not work, causing the compressor, evaporator, and shell and tube heat exchanger pipes in the system of the unit to freeze and crack, making the entire water heater scrapped.

[0003] In order to reduce the risk of heat pumps being damaged by freezing, existing air source heat pumps often prevent the unit from freezing and cracking by allowing the hot water in the water tank to circulate automatically and regularly between the water tank and the main unit, and using the hot water in the water tank to heat the valves, pipes, water pumps and unit heat exchangers. However, when a power outage occurs, the temperature of the hot water drops rapidly in the north and other cold regions. If the heat pump failure is not discovered in time, the freezing and cracking severity of the pipes and units will increase after the hot water cools down. For this reason, we propose an air source heat pump antifreeze device that can increase the cooling time of the antifreeze liquid. Utility Model Content
