Problems solved by technology

The environmental temperature control status of the traditional computer room is: 1. The cooling redundancy caused by the high temperature in the local area caused by the dead angle of the temperature-controlled air circulation in the computer room; 3. Cooling capacity caused by radiant heat caused by imperfect building insulation

Embodiment 1

[0019] Embodiment 1: As shown in the figure, this kind of machine room energy-saving dual-cycle system includes a heat exchanger 1, a heat exchanger cabinet 3 and an energy-saving cabinet 2 arranged outside the computer room 5, and the energy-saving cabinet 2 Including cabinet upper air cavity 2-1, equipment installation unit 2-2, cabinet lower air cavity 2-3, temperature controlled exhaust unit 2-4 and temperature controlled air supply unit 2-7, said temperature controlled exhaust unit 2- 4 Including the main exhaust fan 2-4-1, at least one temperature-controlled exhaust outlet 2-4-2, maintenance air supply outlet A2-4-4, and the process associated with the temperature-controlled exhaust outlet 2-4-2 At least one air volume controller A2-4-3 for air volume control. The temperature-controlled air supply unit 2-7 includes a main blower 2-7-1, at least one temperature-controlled air supply port 2-7-2, a maintenance air supply port B2-7-4, and the temperature-controlled air supply...

Embodiment 2

[0022] Example 2: Such as figure 2 As shown, the difference from Embodiment 1 is: the heat exchange device 3-2 is equipped with an air-conditioning evaporator 4-1, and the air-conditioning evaporator 4-1 is installed in the indoor evaporator 1-1 of the heat exchanger. On one side, the air conditioner evaporator 4-1 is connected to the outdoor condenser of the air conditioner 4 outside the machine room 5 through a pipe to form a circulating pipe for auxiliary heat dissipation. In the case of low heat exchange efficiency, the air conditioner 4 serves as an auxiliary refrigeration system to perform auxiliary refrigeration processing on the wind entering the lower air cavity 3-3 in the heat exchange device 3-2.

Abstract

The invention relates to an energy-saving double-circulation system of a machine room. The energy-saving double-circulation system comprises a heat exchanger, a heat exchange cabinet and energy-saving cabinets, wherein each energy-saving cabinet comprises an upper air cavity of the cabinet, an equipment mounting unit, a lower air cavity of the cabinet, a temperature control exhaust unit and a temperature control air supply unit, a plurality of the energy-saving cabinets are sequentially connected in series and then connected with the heat exchange cabinet, the lower air cavities of the cabinets and the lower air cavity of the heat exchange cabinet are used for transferring cold air, the cold air in the lower air cavities of the cabinets can form hot air in the upper air cavity of the heat exchange cabinet after passing the equipment mounting unit for heat exchange, and the upper air cavities of the cabinets and the upper air cavity of the heat exchange cabinet are used for transferring the hot air, so that a closed internal circulation air passage is formed; and an indoor evaporator is connected with an outdoor condenser of a heat exchanger outside the machine room through a cooling medium pipeline for constituting an external circulation pipeline of a heat exchange system. The energy-saving double-circulation system disclosed by the invention has the benefits that, refrigeration internal circulation with equipment precise temperature control, which is only designed against equipment subject to temperature control, can specially perform control according to temperature heat radiation requirements of different equipment, and every energy-saving cabinet can be controlled independently.

Description

Technical field [0001] The invention relates to the energy-saving field of electrical equipment in a computer room, in particular to an energy-saving double-circulation system in a computer room. Background technique [0002] The main feature of the electrical equipment room is: a large number of electrical equipment is built in the computer room, and the electrical equipment runs unattended for a long time. The time for personnel in the equipment room to actually enter the equipment room for equipment maintenance is very short. In order to ensure that the electrical equipment in the computer room works normally in a suitable environment, a computer room air conditioner is installed in the computer room to adjust the ambient temperature in the computer room to ensure that various electrical equipment in the computer room are at a suitable working environment temperature. Since the electrical equipment in the computer room operates 24 hours a day, and the air conditioner in the c...
