Operation principle of the present utility model is as follows.
(1) heat pipe operation principle
In summer, the liquid refrigerant in heat exchanger 1 is because Action of Gravity Field accumulates in bottom, and new distinguished and admirable during through its bottom when outdoor high temperature, inner liquid refrigerant is just subject to thermal evaporation, and overpressure is increased, and steam flows to top; The high steam that absorbs heat in heat exchanger 1 flows to the top of low pressure heat exchanger 2 11 through tube connector 6, because the new air temperature on heat exchanger 2 11 tops of flowing through is lower, steam absorbs heat in heat exchanger 2 11, be condensed into liquid, then due to Action of Gravity Field, accumulate in the bottom of heat exchanger 2 11, finally by the bottom of tube connector inflow heat exchanger 1, circular flow.
In the winter time, gaseous working medium accumulates in the top of heat exchanger 1, because the new air temperature on heat exchanger one 4 tops of flowing through is lower, working substance steam is by the condensation of the new wind of low temperature institute, become liquid refrigerant, the top from heat exchanger 1 under Action of Gravity Field accumulates to its bottom, then through tube connector, gets back to the bottom of heat exchanger 2 11, new distinguished and admirable through its bottom due to high temperature, liquid working medium is subject to thermal evaporation, becomes steam, and pressure raises, get back to the top of heat exchanger 1, circular flow.
This process constantly circulates, and constantly by the heat in new wind (summer) or cold (winter) transfer back and forth, has reduced the work load of evaporimeter or condenser, has improved the operating efficiency of heat pump, has realized energy-conservation object.
(2) evaporative cooling operation principle
In summer, from full-heat-exchange equipment 3, unsaturated indoor return out, when condenser 22, contacts with the condensed water under rotary nozzle 21 sprays, because the partial pressure of steam in return air is less than the partial pressure of steam in condensed water, condensate evaporation.Condensation evaporation of water need to absorb the heat of high temperature that a large amount of refrigeration working mediums discharges, and is evaporated to steam, and then steam is discharged by exhaust blower with return air.
Through relevant research, show, evaporative cooling heat transfer effect will be far above air-cooled and water-cooled, moreover condensate temperature of the present utility model is relatively low, can increase substantially the refrigerating efficiency of heat pump, realizes energy-efficient.
(3) operation condition in summer
Referring to Fig. 1, after outdoor new wind 1 passes through respectively new wind filter 2 and return air filter 17 primarily efficient filters with indoor return air 16, the two enters in full-heat-exchange equipment 3 carries out caloic exchange, and new air temperature is reduced, and return air temperature raises; From full-heat-exchange equipment 3, new wind is out through after heat exchanger 1, and temperature reduces again, and then new wind enters in evaporimeter 7, and the processing that is further cooled, reaches mechanical dew point; The new wind of low temperature after processing enters and in heat exchanger 2 11, is heated to wind pushing temperature (if the new air temperature of processing through heat exchanger 2 11 is when setting value, electronic by-passing valve 13 can be according to setting value automatic regulating valve door aperture, make the state of new wind reach setting value), finally by pressure fan 14, the new wind that reaches ventilation state is sent into air-conditioned room.
Return air temperature after full-heat-exchange equipment 3 is processed raises, and then enters in condenser 22; Cryogenic condensation water under return air sprays with rotary nozzle 21 in condenser 22 carries out caloic exchange, and absorptive condenser heat, finally by outside exhaust blower discharge chamber.
The condensed water that water receiving tank 1, water receiving tank 28, water receiving tank 3 12 and indoor condensed water are 15 li is pooled in condensation water tank 9, and then condensed water is sent in rotary nozzle 21 after condensate pump 20 pressurizations again, finally sprays on condenser coil equably.
(4) winter operation operating mode
Referring to Fig. 2, when the utility model moves in the winter time, heat pump, by the commutation effect of four-way change-over valve, takes a turn for the worse refrigerant flow direction.Evaporimeter 7 in Fig. 1 in heat pump and condenser 22 become respectively condenser 7 and the evaporimeter 22 of heat pump in Fig. 2.
After outdoor new wind 1 passes through respectively new wind filter 2 and return air filter 17 primarily efficient filters with indoor return air 16, the two enters carries out caloic exchange in full-heat-exchange equipment 3, thereby new air temperature is raise, and return air temperature reduces; From full-heat-exchange equipment 3, new wind is out through after heat exchanger 1, and temperature raises again, and then new wind enters in condenser 7, is further warmed processing; The new wind of high temperature after processing enters and in heat exchanger 2 11, is cooled to wind pushing temperature (if the new air temperature of processing through heat exchanger 2 11 is when setting value, electronic by-passing valve 13 can be according to setting value automatic regulating valve door aperture, make the state of new wind reach setting value), finally by pressure fan 14, the new wind that reaches ventilation state is sent into air-conditioned room.
Return air temperature after full-heat-exchange equipment 3 is processed reduces, and then enters in evaporimeter 22; In evaporimeter 22, be absorbed heat, temperature reduces, finally by outside exhaust blower discharge chamber.
Condensed water in water receiving tank 1, water receiving tank 28, water receiving tank 3 12 and indoor condensed water 15 is pooled in condensation water tank 9, and condensed water is discharged from condensation-water drain through condensation bypass pipe 10 again, and condensate pump quits work.
(5) operating mode of excessively ventilating season
Source pump, condensed water recycling device and heat pipe quit work; New wind and return air carry out after caloic exchange, and new wind is directly sent into indoor by pressure fan; Full-heat-exchange equipment 3 also quits work, and realizes all-fresh air air-supply.
The various embodiments described above are only for illustrating the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
