Dual-cycle machine room energy-saving air conditioner

Abstract

The invention provides a dual-cycle machine room energy-saving air conditioner which comprises an evaporator arranged in a machine room as well as a condenser, a compressor, a three-way valve, a first intermediate heat exchanger and a second intermediate heat exchanger which are arranged outside the machine room, wherein the three-way valve comprises a first inlet, a second inlet and an outlet, and the outlet is alternatively communicated with the first inlet or the second inlet; and the alternative communication of the three-way valve can realize the switching between a heat-tube heat exchange mode and a compression refrigerating cycle heat exchange mode. The dual-cycle machine room energy-saving air conditioner can flexibly select one heat exchange mode according to the temperature difference between the interior and the exterior of the machine room, thereby effectively solving the heat extraction problem of the machine room and achieving the advantages of low energy consumption, high reliability and long service life.

Description

technical field The invention relates to the field of energy-saving air conditioners for computer rooms, in particular to a double-cycle energy-saving air conditioner for computer rooms. Background technique Due to the high heat generated by the equipment in the computer room, special air-conditioning equipment is required to maintain the temperature in the computer room. At present, the existing computer room generally adopts the continuous operation of the comfort air conditioner to regulate the indoor temperature. Although this temperature control method can meet the temperature control requirements of the computer room, it consumes a lot of energy, resulting in high operating costs. At present, there are two main energy-saving technologies for computer room air conditioners: One is to introduce outdoor fresh air to cool the equipment in the equipment room during the transitional season or when the outdoor temperature is relatively cool in winter. This kind of equipm...

Problems solved by technology

Since the heat exchanger adopts a honeycomb structure, the air flow channel is easily blocked by dust, so filters need to be installed at the inlet and outlet of the outdoor air flow channel, and the maintenance is relatively large
