The design principle that heat pump unit is used in combination with source of sewage titanium exchanger heats circulation as shown in Figure 1:, and compressor is absorption
The refrigerant of heat enters condensation exchanger by four-way reversing valve from exhaust outlet and heat is exchanged water supply, the refrigerant that cools from
Heat exchanger, which comes out, passes through fluid reservoir, and condensed hydrops is stored in fluid reservoir, and fluid reservoir mountain pass is divided into two-way, is passed through all the way
The heat in air, another way, after heating power expansion valve is depressured are absorbed to air-cooled recirculation type evaporator after electric expansion valve decompression
Heat is absorbed to cesspool, two-way absorbs the refrigerant of heat finally with being compressed by the compressor to compressor return air mouth, from exhaust
Mouthful row mountain, as soon as it completes to absorb heat and discharges the circulation of heat as shown in Figure 1, when unit conversion refrigerating operaton will appear effect
The possibility of rate decline and system jams.The key point for causing efficiency to decline does not work in fourth fluid reservoir, because refrigerant passes through wind
It is directly connect with electric expansion valve after air-cooled condenser, fluid reservoir does not work, and will lead to condensed cooling medium liquid volume and lives wind
The bottom of air-cooled condenser is accumulated equal to the heat exchange for reducing condenser, therefore unit refrigerating efficiency is caused to decline.System jams
Key point be that opening for electronic expansion net forward direction circulation reads pressure difference greater than 3.2Pa, and that inversely circulates opens the big fourth of network pressure difference
0.75Pa, electric expansion valve is in reverse circulation when unit freezes, and electronic expansion inlet outlet pressure differential is substantially exceeded by actual measurement
0.75Pa results in electric expansion valve to be possible to not open valve, causes the stifled match of refrigeration system.
