Problems solved by technology

[0003] In recent years, in order to save the energy consumption of the air conditioner in the computer room, the natural cooling source is used for cooling in winter when the temperature is low, and the air conditioner compressor is still used for cooling in other seasons. Since a large part of the year is used for compressor cooling, therefore, high energy consumption

[0076] Such as figure 2 As shown, the second embodiment of the cooling control system of the machine room of the present invention also includes:

[0077] A first flow direction control valve 8 arranged in parallel with the circulation pump 3 through the first bypass;

[0078] When the circulation pump 3 is turned on, the circulation pump 3 pumps the refrigerant into the throttling element 4;

[0079] When the circulation pump 3 is turned off, the refrigerant enters the throttling element 4 through the first flow direction control valve 8 .

[0080] In the technical scheme of the present invention, as figure 2 As shown, a first bypass with a first flow direction control valve 8 is added outside the inlet and outlet of the circulation pump 3 of the refrigeration control system in the first embodiment, and the temperature sensor and control device are not shown: when only the compressor works mode, the compressor 1 and the first flow direction control valve 8 are opened, an...

no. 3 example

[0081] Such as image 3 As shown, the third embodiment of the refrigeration control system of the machine room of the present invention also includes:

[0082] A second flow direction control valve 9 arranged in parallel with the compressor 1 through a second bypass;

[0083] When the compressor 1 is turned on, the refrigerant enters the condenser 2 after being compressed by the compressor 1;

[0084] When the compressor 1 is turned off, the refrigerant enters the condenser 2 through the second flow direction control valve 9 .

[0085] In the technical solution of the present invention, as image 3 As shown, a second bypass with a second flow direction control valve 9 is added outside the inlet and outlet of the circulation pump 3 of the refrigeration control system in the first embodiment, and the temperature sensor and control device are not shown: when only the circulation pump works In the mode, the compressor 1 is closed, because the resistance of the refrigerant passi...

Abstract

The invention relates to the technical field of refrigeration equipment and discloses a refrigeration control method, device and system of a machine room. The refrigeration control system comprises a compressor, a condenser, a circulating pump, a restricting element, a evaporator, a temperature sensor and a control device, wherein the compressor, the condenser, the circulating pump, the restricting element and the evaporator are sequentially connected through a pipeline to form closed circulation, refrigerating fluid is in the pipeline, the condenser is arranged outdoors, the temperature sensor is arranged outdoors and used for detecting outdoor temperature information, the control device is in signal connection with the temperature sensor, the circulating pump and the compressor, and the control device is used for controlling opening and closing of the circulating pump and controlling opening the closing of the compressor when the outdoor temperature is higher than a first temperature threshold value and lower than a second temperature threshold value. The refrigeration control system saves energy and improves the energy utilization rate of the machine room.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration control method, device and system for a machine room. Background technique [0002] With the development of modern information technology, the number and scale of communication equipment rooms across the country are also expanding. At the same time, under the call of the national energy conservation and emission reduction policy, reducing energy consumption in equipment rooms has become the focus of many operators. According to the survey, in the computer room, only the power consumption of the precision air conditioner accounts for more than 50% of the total power consumption of the computer room. About 70%. Therefore, effectively reducing the power consumption of air conditioners has become an important direction to reduce the energy consumption of computer rooms. [0003] In recent years, in order to save the energy consumption of the air cond...
