Detailed description of the invention
1 pair of this utility model is described in detail below in conjunction with the accompanying drawings:
A kind of direct-expansion type heat pump Radiant Floor Heating System, heat pump compressor 1 exhaust side is connected with three-way valve 2 entrance, and three
Logical valve 2 second outlet is connected with the 3rd electromagnetic valve 11, and the 3rd electromagnetic valve 11 is connected with fin-tube heat exchanger 9 arrival end；
Three-way valve 2 first outlet is connected with the first electromagnetic valve 3, and grounding heat coil tube 4 arrival end and the first electromagnetic valve 3 are connected, ground
Warming plate pipe 4 port of export and the second electromagnetic valve 5 are connected, and the second electromagnetic valve 5 is connected with reservoir 6 arrival end again, reservoir 6 port of export
Then being connected with device for drying and filtering 7 arrival end, device for drying and filtering 7 port of export is connected with electric expansion valve 8 entrance, electric expansion valve 8
The port of export is directly connected with fin-tube heat exchanger 9 arrival end, and fin-tube heat exchanger 9 port of export is then inhaled with heat pump compressor 1
Gas side is connected.
The windward side of fin-tube heat exchanger 9 is provided with blower fan 10.
Its work process is as follows: the high-temperature gas cycle fluid that heat pump compressor is discharged flows into indoor through the first electromagnetic valve
Grounding heat coil tube, heats coil pipe, and then heats the floor above the coil pipe that is laid in, and makes floor surface temperature be higher than Interior Space temperature
Degree, floor starts to transfer heat to room air in the way of radiant heat transfer, makes indoor air temperature raise, it is achieved heating；From ground
The working medium that warming plate pipe flow goes out condenses because of heat release becomes liquid refrigerant, through the second electromagnetic valve, reservoir and device for drying and filtering, and
After electric expansion valve reducing pressure by regulating flow, become low temperature liquid working medium enter fin-tube heat exchanger, air in absorption chamber external environment
After energy, gasification becomes low-pressure gaseous working medium, and after low-pressure gaseous working medium is sucked by heat pump compressor, increasing temperature and pressure becomes high-temperature gas
Working medium, enters next one heating circulation；Reservoir is for storing unnecessary liquid refrigerant, to meet when heat load changes following
The needs of ring working medium flow regulation；Device for drying and filtering can remove a small amount of moisture and mechanical admixture being mixed with in heating system pipeline,
Avoid the occurrence of blocking accident；When outside ambient air temperature is too low, if fin-tube heat exchanger frosting is serious, will cause
Cycle fluid heat absorption deficiency, thus reduce heating capacity, now can start defrosting pattern: close the first electromagnetic valve and the second electricity
Magnet valve, and open the 3rd electromagnetic valve, the high-temperature gas working medium now discharged from heat pump compressor is bypassed by the 3rd electromagnetic valve
To fin-tube heat exchanger, carry out heating defrosting；No matter being in heating mode or defrosting pattern, starting fan operation can strengthen
The heat transfer effect of fin-tube heat exchanger.
