Abstract

The invention discloses a microchannel propane direct expansion solar heat pump water heater, which belongs to the field of solar heat pump and energy heating. It includes heat collector, condenser, heat storage tank, electronic expansion valve, compressor and related connecting pipelines. The heat collector includes header one and several microchannel pipelines. The adjacent microchannel pipelines pass through the collector Once the tubes are connected, a vacuum glass tube is placed outside each microchannel pipeline. The microchannel pipeline is an arc-shaped flat tube, and its concave surface of the arc faces the sunlight, and the vacuum glass tube is facing the convex surface of the microchannel pipeline. Reflective paint is applied on the inner surface side of the microchannel pipeline, and the reflective paint is used to collect the unused sunlight leaked from the gaps on both sides of the microchannel pipeline by using the reflective paint in the vacuum glass tube and reflect it to the convex side of the microchannel pipeline for secondary use. In the present invention, each component optimizes and controls energy utilization, reduces energy loss in an all-round way, and has the advantages of high equipment utilization rate, remarkable energy saving and environmental protection effect, and the like.

Description

technical field [0001] The invention belongs to the field of solar heat pump and energy heating, and relates to a solar water heater, in particular to a microchannel propane direct expansion solar heat pump water heater. Background technique [0002] Building energy consumption such as domestic hot water, air conditioning, and heating accounts for more than one-fifth of the country's commodity energy consumption. Energy conservation and emission reduction, as an important topic that can achieve energy conservation, pollution control and improve energy utilization efficiency after finding new energy sources, has become an important means to solve environmental problems, achieve rapid economic growth and prolong the search time for new energy sources. The existing products of solar collectors in my country have problems such as low energy utilization efficiency in terms of glass transmittance, high-efficiency selective coating, overall structural design and production technolo...
