Abstract
The invention discloses a novel energy-saving air-cooled chiller unit and belongs to the technical field of refrigeration machinery. A conventional full-year refrigeration air-cooled chiller unit needs to start compressors with the largest proportion of power consumption of the unit to achieve refrigeration circulation when the conventional full-year refrigeration air-cooled chiller unit runs for refrigeration in the cold winter. The novel energy-saving air-cooled chiller unit comprises a compressor, an air-cooled condenser, a liquid storage tank, a throttling device and an evaporator, wherein the air-cooled condenser is connected to the high pressure side of the compressor, and the evaporator is connected to the low pressure side of the compressor. The novel energy-saving air-cooled chiller unit is characterized in that the throttling device is in parallel connection with a solution pump for delivering a liquid refrigerant. When the ambient temperature is low in winter, the compressor stops, and the solution pump starts to drive the refrigerant to circulate between the evaporator and the condenser to further release the refrigeration capacity of the low-temperature outdoor air to the refrigeration water so as to reduce the temperature of the refrigeration water to achieve the purpose of refrigeration. The novel energy-saving air-cooled chiller unit greatly reduces the power consumption of the unit operation and achieves significant energy saving effects.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described.
As shown in Figure 1, novel energy-saving cooling by wind of the present invention, 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 invention 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.
