Description

Technical Field

[0001] The utility model relates to the field of solar heat pumps, in particular to a new trough-type solar heat pump cold and hot supply pipeline structure. Background Art

[0002] At present, there are three types of solar thermal technologies that can be commercialized in the world: trough solar thermal technology, tower solar thermal technology and dish solar thermal technology. The combined cooling and heating pipe of the solar heat pump is one of the main core equipment of the trough solar thermal system.

[0003] The hot water pipeline and the cold water pipeline of the existing combined heat and cold supply pipe are both arranged outside the hot water tank, so the switch valves on the hot water pipeline and the cold water pipeline are also exposed. When it rains, rainwater will fall on the switch valves of the hot water pipeline and the cold water pipeline, which will cause the switch valves to be corroded over time, thus causing the switch valves to fail and making the combined heat and cold supply pipeline unable to pass water. Therefore, a new combined heat and cold supply pipeline structure of a trough-type solar heat pump is proposed. Utility Model Content
