Description

Technical Field

[0001] The utility model relates to the technical field of heat pump protection equipment, and more specifically, to a heat pump host water pump thermal insulation protection device. Background Art

[0002] Heat pump is a high-efficiency energy product widely used in heating, cooling and hot water supply. There are some problems in the design of the water circuit of the existing heat pump system.

[0004] However, the prior art accommodates multiple devices together with a water pump in an insulation shell. There is a large gap between the water pump and other devices and the wall of the insulation shell, and water vapor is easily generated and retained in a humid environment. When the water vapor meets the cold wall of the water pump body, condensation water will form. If the condensation water cannot be discharged in time, it will cause the water pump to malfunction due to water immersion. There are technical problems such as poor insulation effect and easy water immersion malfunction of the water pump. Utility Model Content
