Micro channel condenser for circulating type air source heat pump water heater

Abstract

The invention discloses a micro channel condenser for a circulating type air source heat pump water heater. According to the micro channel condenser for the circulating type air source heat pump waterheater, refrigerant micro channel flat tubes are adopted to be parallelly arranged between a first refrigerant flow collecting tube and a second refrigerant flow collecting tube, a first water flow collecting tube and a second water flow collecting tube both communicate with a plurality of water flow dividing tubes, each water flat tube is sleeved on the outer side of each refrigerant micro channel flat tube to form a sleeve type structure, end covers penetrate through the refrigerant micro channel flat tubes to be welded to the two ends of each water flat tube to make the two ends of a ring-shaped water flow channel be closed, and a refrigerant air inlet tube and a refrigerant liquid outlet tube are connected with corresponding pipelines inside an air source heat pump system correspondingly to make a refrigerant perform circulation flowing inside the system. The micro channel condenser for the circulating type air source heat pump water heater is simple in structure, easy to machineand convenient to install; by means of an all-aluminum material lightweight design, recycling is performed easier, and circulation use is performed; by means of micro channel flat tube structures, therefrigerant side heat exchange coefficient is enhanced, the refrigerant filling quantity is reduced, and the micro channel condenser for the circulating type air source heat pump water heater can beused for higher pressure systems; and by means of the sleeve type structure, water and the refrigerant can be made to form pure countercurrent heat exchange, so that the heat transfer temperature difference is increased, and the heat transfer quantity is increased.

Description

Technical field [0001] The invention relates to the technical field of heat pump equipment, and more specifically to a microchannel condenser for a circulating air source heat pump water heater. Background technique [0002] Air energy is a new energy developed and widely used by mankind after wind, solar, and tidal energy. It not only has a high energy efficiency ratio, but is also low-carbon and environmentally friendly. After use, it does not produce harmful gases or emit carbon dioxide. More importantly, it has Renewability, inexhaustible, inexhaustible, with high utilization value, is a key new energy that actively encourages development and utilization in China. The air source heat pump water heater using air energy has high energy efficiency and significant energy saving effect, and the operating cost is much lower than other traditional heat source heat backup (coal boiler, oil boiler, electric boiler). The cost of using air to heat the same weight of water in the same e...
