Indirect evaporation cooling and heat pipe dual-power combined system and control method

Abstract

The invention discloses an indirect evaporation cooling and heat pipe dual-power combined system and a control method. The indirect evaporation cooling and heat pipe dual-power combined system comprises an indirect evaporation cooling system and a DX heat pipe compensation system, the DX heat pipe compensation system comprises a DX compensation system and a gravity assisted heat pipe system, and the indirect evaporation cooling system, the DX compensation system and the gravity assisted heat pipe system are independently controlled by starting and stopping mechanisms; the DX compensation system comprises a DX evaporator, and the gravity assisted heat pipe system comprises a heat pipe evaporator and a heat pipe condenser; the DX evaporator and the heat pipe evaporator are installed indoorsand share an indoor air supply fan of the indirect evaporation cooling system; the heat pipe condenser is installed outdoors, and the installation height of the heat pipe condenser is larger than thatof the heat pipe evaporator; and the DX evaporator and the heat pipe evaporator are both used for absorbing heat supplied to the indoor space by an indoor air supply fan. The indirect evaporation cooling and heat pipe dual-power combined system has multiple refrigerating operation modes, the requirement for indoor refrigerating capacity under different outdoor working conditions can be met, an outdoor natural cold source is fully utilized, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an indirect evaporative cooling and heat pipe dual power combined system and a control method. Background technique [0002] The increasing demand for energy conservation, emission reduction and green environmental protection worldwide has put forward higher requirements for the construction and operation of data centers, which consume the most energy in the IT industry. The reduction of the PUE value of data centers has become the primary appeal of owners and design builders. [0003] For the traditional compressor refrigeration mode, because the power consumption of the compressor is generally relatively large, the energy consumption of the overall computer room air conditioner will be very high, resulting in a significant increase in maintenance costs in the computer room; and for the traditional indirect evaporative cooling air conditioner, due to In winter, when the o...

[0003] For the traditional compressor refrigeration mode, because the power consumption of the compressor is generally relatively large, the energy consumption of the overall computer room air conditioner will be very high, resulting in a significant increase in maintenance costs in the computer room; and for the traditional indirect evaporative cooling air conditioner, due to In winter, the outdoor temperature is too low, and the heat exchange between the indoor return air and the outdoor return air may cause condensation on the air-to-air heat exchanger and cause water to enter the interior of the equipment room, greatly affecting the reliability of the equipment in the equipment room.
