Photovoltaic-drive heat pipe combined machine room air conditioning unit

Abstract

The invention discloses a photovoltaic-drive heat pipe combined machine room air conditioning unit. The machine room air conditioning unit is characterized in that photovoltaic power and power grid power are complemented to realize the dual-energy power supply of the machine room air conditioning unit, wherein a machine room air conditioning outdoor unit consists of a heat pipe unit and a cooling unit, which are combined; the heat pipe unit consists of an indoor evaporator, a heat pipe electromagnetic valve, a heat pipe condenser, a second intermediate heat exchanger channel, a liquid storage device and a Freon pump, which are sequentially arranged and form a heat pipe working medium circulation loop; the cooling unit comprises a variable frequency compressor and a cooling condenser connected to one side of an exhaust port of the compressor; at an outlet of the cooling condenser, double circulation loops are formed, one loop is formed sequentially by an auxiliary way electromagnetic valve, a first throttling mechanism and a first intermediate heat exchanger channel, and the other loop is formed sequentially by a main way electromagnetic valve, a second throttling mechanism, the indoor evaporator and a cooling electromagnetic valve. according to the machine room air conditioning unit, light energy and a natural cooling source can be maximally utilized, the air of a machine room can be conditioned around the clock, energy is greatly saved, and emissions are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a photovoltaic-driven heat pipe composite air-conditioning unit capable of maximizing the utilization of outdoor natural energy and a control method thereof. Background technique [0002] With the rapid development of the information industry and digital construction, the number of computer rooms and base stations has increased rapidly. According to statistics, the energy consumption of air conditioners in computer rooms and base stations accounts for more than 40% of the total energy consumption. The data center has a large sensible heat load, a closed enclosure structure, and operates around the clock throughout the year. In sunny summer or transitional seasons, if natural energy can be used to alleviate or even replace the power consumption of the vapor compression refrigeration system, the energy consumption of the air conditioning system will be greatly reduced. con...
