Description of drawings
Below, contrast accompanying drawing and preferred embodiment are elaborated to the utility model, wherein:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, pump circulating energy-saving air conditioner component indoor A and outside B two parts of the utility model proposes.The indoor comprises compressor 1, evaporimeter 13, expansion valve 12 etc., and the outside comprises condenser 4, reservoir 6, circulating pump 7 etc., and indoor and outside couple together by tube connector.
The utlity model has two kinds of refrigerating operaton patterns of compression mechanism cold operation and pump circular flow, two kinds of refrigerating operaton patterns can automatically switch by magnetic valve according to factors such as heat load sizes in outdoor environment temperature, the machine room, to reach refrigeration system optimum operation efficiency.
At outdoor environment temperature higher or indoor/outdoor temperature-difference less in, with the compressor cooling mode operation, circulating path is: compressor 1--check (non-return) valve 2--condenser 4--check (non-return) valve 5--check (non-return) valve 9--magnetic valve 10--expansion valve 12--evaporimeter 13--magnetic valve 14--vapour liquid separator 15--compressor 1, finish a circulation.In compressor operating, the demand of cold-producing medium does not have pump circulation so much, and unnecessary cold-producing medium will be stored in the reservoir 6 with the parallel connection of compression refrigeration circulation stream.When compressor 1 and circulating pump 7 switch, in the evaporimeter 13 a large amount of refrigerant liquids will be arranged, therefore, before compressor, increase a vapour liquid separator 15, when avoiding compressor start, a large amount of refrigerant liquids enter compressor, improve the reliability of compressor operating.
At outdoor environment temperature lower or indoor/outdoor temperature-difference bigger in, move with the circulating pump refrigeration mode, circulating path is: circulating pump 7--check (non-return) valve 8--magnetic valve 11--evaporimeter 13--check (non-return) valve 3--condenser 4--check (non-return) valve 5--circulating pump 7, finish a circulation.In pump operating cycle, store certain refrigerant liquid all the time in the reservoir 6 in parallel with pump circulation stream, because the liquid level discrepancy in elevation of reservoir and pump inlet provides certain static pressure pressure reduction, cavitation can not appear in the time of can guaranteeing pump operating cycle.The liquid level of reservoir must be considered the net positive suction head of circulating pump itself and the reservoir resistance to pipeline between pump inlet.In order to ensure there being certain refrigerant liquid in the reservoir all the time, between reservoir and condenser, increased check (non-return) valve 5, when guaranteeing that compressor or circulating pump are shut down, the refrigerant liquid in the reservoir can not be back in the condenser 4.When heat load changes in the indoor units of different capabilities and the machine room, the refrigerating capacity that requires circulating pump to provide, promptly the refrigerating capacity flow is different, therefore, the cold-producing medium circulating pump has adopted frequency conversion or pressure-adjusting type circulating pump, reaches the Optimal Control to refrigerant flow.
Energy-saving effect of the present invention is remarkable, unit with 60kW is an example, under identical refrigerant flow condition, the power of pump operating cycle only is about 6% of the compressor horsepower that moves under the same environmental condition under frequency conversion or pressure regulation drive, for the unit of bigger refrigerating capacity, the energy saving of pump circulation is just more obvious.
