Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described further.
As shown in Figure 1, novel energy-saving cooling by wind of the present utility model, comprise and being connected in circulating refrigerant loop and compressor 1, air-cooled condenser 4, fluid reservoir 6, throttling arrangement 10, the evaporimeter 12 arranged according to the flow direction of circulating refrigerant, air-cooled condenser 4 is connected to the high-pressure side of compressor 1, evaporimeter 12 is connected to the low-pressure side of compressor 1, throttling arrangement 10 is parallel with solution pump 8 for conveying liquid cryogen, solution pump 8 is Liquid transfer instruments of a kind of similar water pump.
Concrete, solution pump 8 is positioned at fluid reservoir 6 bottom.Be connected with device for drying and filtering 7 between fluid reservoir 6 and throttling arrangement 10, import and fluid reservoir 6 bottom of device for drying and filtering 7 are connected, and the outlet of device for drying and filtering 7 is divided into two-way, and a road connects throttling arrangement 10, and another road connects solution pump 8.Further, throttling arrangement 10 comprises the C check valve 9 being positioned at its inlet side, C check valve 9 only allows circulating refrigerant to be flowed to throttling arrangement 10 by air-cooled condenser 4, solution pump 8 comprises the D check valve 11 being positioned at its outlet side, D check valve 11 only allows circulating refrigerant to be flowed to evaporimeter 12 by solution pump 8, and C check valve 9, the throttling arrangement 10 of series connection form parallel connection with the solution pump 8 of connecting, D check valve 11.Being connected with A check valve 2, A check valve 2 between compressor 1 and air-cooled condenser 4 only allows circulating refrigerant to flow to air-cooled condenser 4 by compressor 1.On compressor 1, A check valve 2, B check valve 3, a B check valve 3 in parallel only allows circulating refrigerant to be flowed to air-cooled condenser 4 by evaporimeter 12.
As shown in the figure, the concrete annexation of novel energy-saving cooling by wind of the present utility model is: connect bottom device for drying and filtering 7 import and fluid reservoir 6; Device for drying and filtering 7 outlet is divided into two-way, connects solution pump 8 import and C check valve 9 import respectively.Solution pump 8 outlet is connected with D check valve 11 import, and C check valve 9 outlet is connected with throttling arrangement 10 import, and D check valve 11 exports to export with throttling arrangement 10 again and is connected.Compressor 1 exhaust outlet is provided with the outlet of A check valve 2, A check valve 2 and exports with B check valve 3 and be connected, and B check valve 3 import is connected with compressor 1 air entry.Namely B check valve 3 and compressor 1, A check valve 2 are connected in parallel.
