Introduce the operation principle of this device below:
Process of refrigerastion, first, low-temp low-pressure gas refrigerant when frequency converting air-conditioner compressor suction, through compressor output high temperature and high pressure gas, enter condenser 3, with the external world carry out heat exchange obtain middle pressure in warm refrigerant liquid, when cold-producing medium flows out condenser, through unsteady flow throttling arrangement, open completely, enter conveyance conduit.Now, unsteady flow throttling arrangement is opened completely, liquid refrigerant is again through the refrigeration check valve apparatus with throttling function near evaporator inlet end, refrigeration check valve apparatus conducting direction points to condenser, now, by refrigeration check valve apparatus, by unsteady flow, swash and penetrate ejection, moment step-down, cold-producing medium is vaporized rapidly, enter again evaporimeter, the advantage arranging is like this: (1) is due to refrigeration check valve apparatus is located near on the conveyance conduit of evaporimeter, reduced cold-producing medium in conveying with extraneous heat exchange, thereby under equal conditions than conventional throttle, there is better refrigeration, (2) because cold-producing medium in intake line changes to liquid input by gaseous state, the gaseous state of equal in quality is larger than the liquid space occupying, and therefore liquid conveying increased condensation space, therefore reduced compressor delivery pressure, thereby reduced the power consumption of compressor.In sum, compare with traditional frequency conversion air-conditioning, not only improved refrigerating of convertible frequency air conditioner amount, also reduced compressor power consumption simultaneously.In when refrigeration in the middle of convertible frequency air-conditioner enters, the aperture by adjusting electric expansion valve is to obtain best refrigerating efficiency.Energy Efficiency Ratio when this process has improved refrigerating of convertible frequency air conditioner.
Heat process, the process of heating can be regarded the contrary circulation of process of refrigerastion as.
First compressor 1 is exported high temperature and high pressure gaseous refrigerant, through cross valve, switch, enter evaporimeter, carry out heat exchange with indoor environment, at high temperature and high pressure gaseous refrigerant, be cooled to below critical-temperature, cold-producing medium becomes liquid state from gaseous state, and discharging heat energy, realization heats, when the liquid cold-producing medium of evaporimeter 4 output HTHP, by the opposite direction conducting of refrigeration check valve, still with liquid state, flow out.Liquid refrigerant enters condenser 3 vaporizations after the throttling of unsteady flow throttling arrangement, enter condenser 3 cold-producing mediums and in larger space, continue vaporization, absorb heat simultaneously, by condenser 3 and outdoor environment, carry out heat exchange, cryogenic gaseous cold-producing medium after heat exchange, then switch through cross valve 2, by compressor 1, sucked, complete the process of heating, and carry out next circulation by that analogy.Heat in process, can prevent the high pressure liquid refrigerant of being exported by the evaporimeter reduction heating capacity of vaporizing rapidly, therefore can effectively improve the heating energy efficiency ratio of convertible frequency air-conditioner.
More than comprehensive, the refrigeration efficiency of convertible frequency air-conditioner ratio and heating energy efficiency ratio have all improved greatly, therefore, clearly mean that the annual Energy Efficiency Ratio of convertible frequency air-conditioner is carried greatly, have brought beyond thought effect.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
