The micro-channel energy recovery heat exchanger solves the problems that energy is consumed by a motor of a rotary wheel type energy recovery device, and cross contamination is caused by a plate-fin type heat recovery device, and is low in energy consumption, free of maintenance and novel.
Description
Technical field
The utility model relates to a kind of microchannel energy recovering heat exchanger, belongs to air-conditioning technical field, more specifically says for air-air Energy recovery machine set microchannel energy recovering heat exchanger.
Background technology
Air-air Energy recovery machine set is basic rotary-type energy recovery structure or the plate-fin energy recovery structure of adopting at present.Rotary-type energy recovery structure motor rotation need to consume energy and safeguard, windage is larger; And the easy cross pollution of plate-fin energy recovery structure, easy cleaning not, windage is larger.
Summary of the invention
In order to overcome the above-mentioned shortcoming of current air-air Energy recovery machine set, the utility model provides a kind of air-air Energy recovery machine set microchannel energy recovering heat exchanger.
The utility model is achieved by the following technical solution: a kind of microchannel energy recovering heat exchanger, it comprises two upper and lower horizontally disposed, upper micro-channel heat exchanger assembly and lower micro-channel heat exchangers that structure is identical, upper micro-channel heat exchanger is condenser, lower micro-channel heat exchanger is evaporimeter, and two micro-channel heat exchangers link together by intermediate connector; Described micro-channel heat exchanger up and down comprises that header and lower header, a plurality of two ends of equidistantly arranging are vertically welded in the micro-channel flat in header and lower header, is arranged in the middle two ends of micro-channel flat and is vertically welded in a plurality of aluminium fins in header and lower header; The upper header of described two micro-channel heat exchangers up and down connects by tracheae, and lower header connects by liquid pipe; The plug shutoff of the other end of upper header and lower header; Needle valve is housed on tracheae.
Using method and principle are: gas-liquid pipe insulation is processed, and after heat exchanger vacuumizes, fill according to a certain ratio working medium.Summer, in heat exchanger, working medium absorbed new wind-heat amount evaporation current to condenser when higher temperature new distinguished and admirable is during through evaporimeter, and new air temperature reduces; Lower indoor return is when condenser, make the intraductal working medium gas cold liquid that congeals into, the suction force of MCA to liquid, condensation working medium is collected in header, by liquid pipe, be back in evaporimeter, evaporation current is to condenser again for evaporimeter absorbing environmental heat, and so iterative cycles is realized energy recovery
The beneficial effects of the utility model are: air-air Energy recovery machine set is non-maintaining, and without running gear, Non-energy-consumption demand, without cross-infection, reduces the length of unit box body, has reduced cost.
