Operation principle and the process of the embodiment of the present invention are as follows:
The gaseous refrigerant of the HTHP in compressor 8 exits is divided into two-way during heating operation in the winter time: the cross valve 7 of leading up to is connected with indoor heat exchanger 6; Another road is by solution heat exchanger 10, after carrying out heat exchange with the low temperature weak solution, come back to compressor 8, it is that the low pressure refrigerant of outdoor heat exchanger 1 mixes with carrying out flash-pot that the cold-producing medium that this part pressure is higher enters compressor 8, improved pressure and temperature by compressor 8 again, can reduce the pressure ratio of compressor 8 like this, reduce the energy consumption of compressor 8, and can widen the operating condition scope of air source heat pump system.
The cold-producing medium of indoor heat exchanger 6 outlet also is divided into two-way: during heating operation, as regenerated to solution, magnetic valve IV 18 is opened in the winter time, magnetic valve III 19 is closed, cold-producing medium enters solution heat exchanger 10, and enters drier 5 ports after solution generation heat exchange, as shown by the arrows in Figure 2, when solution does not need to be regenerated, magnetic valve IV 18 is closed, and magnetic valve III 19 is opened, the cold-producing medium of indoor heat exchanger 6 outlets directly enters drier 5, enter outdoor heat exchanger 1 through main capillary 2, secondary capillary 3, complete and heat circulation, as shown by the arrows in Figure 3, in summer during refrigerating operaton, the running status of air-conditioning is identical with traditional air-conditioning, as shown by the arrows in Figure 4, compressor 8 is evaporimeter from indoor heat exchanger 6() suck the refrigerant vapour of low-temp low-pressure, be compressed into the gas of HTHP, entering outdoor heat exchanger 1(is condenser), make cold-producing medium be condensed into therein the liquid of normal temperature high voltage, high pressure liquid refrigerant is after main capillary 2 reducing pressure by regulating flows, become low-temp low-pressure liquid, enter evaporimeter through check valve 4, the heat of vaporization that absorbs room air in evaporimeter becomes the steam of low-temp low-pressure, and then sucked by compressor 8, repeat above-mentioned kind of refrigeration cycle, in this process, magnetic valve I 13, magnetic valve II 16, magnetic valve V 17, magnetic valve IV 18 is all closed, magnetic valve III 19 is opened.
Referring to Fig. 1, under heating condition, the spray equipment of outdoor heat exchanger 1 outside is connected successively with NaOH solution tank NaOH 14, magnetic valve I 13, solution pump I 12, forms a closed circuit in the winter time, and cycle fluid is hygroscopic salt solution.When outdoor temperature reaches or during lower than 0 ℃, magnetic valve I 13 is opened, solution pump I 12 is opened, concentrated solution in NaOH solution tank NaOH 14 is passed through the spray head 21 of spray equipment at outdoor heat exchanger 1 surface spraying, air directly contacts with solution and carries out the caloic exchange, solution concentration reduces, and becomes the low temperature weak solution and gets back in NaOH solution tank NaOH 14, continues circulation next time after mixing with original solution.When outdoor heat exchanger 1 surface temperature, during higher than 0 ℃, magnetic valve I 13 is closed, and now solution circulation does not move.
Referring to Fig. 1, Fig. 2, under heating condition, NaOH solution tank NaOH 14 is connected successively with solution pump II 15, magnetic valve II 16, solution heat exchanger 10, regenerator 11, forms a regeneration cycle loop in the winter time, and cycle fluid is hygroscopic salt solution.Magnetic valve II 16 is opened, low temperature weak solution in NaOH solution tank NaOH 14 enters solution heat exchanger 10 through solution pump II 15, now, magnetic valve IV 18 is opened, magnetic valve III 19 is closed, low temperature weak solution and condenser are that the normal temperature high voltage cold-producing medium in indoor heat exchanger 6 exits carries out heat exchange, and solution temperature gets a promotion.Cold-producing medium enters drier 5 after becoming supercooled liquid, after main capillary 2, secondary capillary 3 and outdoor heat exchanger 1 become the refrigerant vapour of low-temp low-pressure, gets back to again compressor 8, has continued the next one and has heated circulation.After the solution temperature at the taphole place of solution heat exchanger 10 gets a promotion, continue to enter regenerator 11, spray is on filler 1104, filler 1104 can increase the contact area of air and solution, surrounding air enters from the bottom of regenerator 11, from top, discharges, and solution and air carry out the caloic exchange, moisture evaporation in solution, need the heat in absorbent solution during evaporation, i.e. the latent heat of vaporization, therefore solution concentration raises, temperature reduces, and becomes concentrated solution and gets back in NaOH solution tank NaOH 14.When indoor heat exchanger 6(is condenser) the cold and hot regeneration demand that can't meet solution of mistake the time, magnetic valve V 17 is opened, and utilizes the heat assisted Regeneration of the part high temperature refrigerant in compressor 8 exits.
In the closed circuit that spray equipment and NaOH solution tank NaOH 14, magnetic valve I 13, the solution pump I 12 of above-mentioned outdoor heat exchanger 1 outside connects and composes successively, continuous circulation along with solution, solution concentration in NaOH solution tank NaOH 14 is more and more lower, for preventing that solution from freezing, solution in NaOH solution tank NaOH has a minimum solution concentration, when the solution concentration in NaOH solution tank NaOH 14 approaches the icing concentration of solution corresponding to environment temperature, solution is by automatic regeneration.Along with constantly carrying out of regeneration, solution concentration is more and more higher, for preventing solution crystallization, solution has a solution concentration the highest, when solution concentration approaches the crystallization concentration of solution corresponding to environment temperature, solution will stop regeneration, now, magnetic valve II 16, magnetic valve V 17, magnetic valve IV 18 are all closed, and magnetic valve III 19 is opened.
Owing to using air-conditioning in the winter time, outdoor temperature is lower, and when outdoor temperature is lower, the efficiency of air-conditioning is also lower, therefore, when outdoor temperature is very low, should not be regenerated to solution, can affect the heating effect of air-conditioning, reduces the air-conditioning service efficiency.In the present invention, the efficient period (being the period that outside air temperature is relatively high) that can be chosen in operation of air conditioner is regenerated to solution, be stored in NaOH solution tank NaOH 14, and when in temperature, lower poor efficiency period is used air-conditioning, can directly use the solution in NaOH solution tank NaOH 14 to be sprayed, do not need to be regenerated, can greatly improve like this average efficiency of air-conditioning, and reduce the whole year operation energy consumption.
