Integral combination type computer room air conditioning unit and control method thereof

Abstract

The invention discloses an integral combination type computer room air conditioning unit and a control method thereof. The air conditioning unit comprises a rotating wheel heat reclaimer, a vapour compression refrigerating system, a fresh air current processing channel, a return air current processing channel and a baffle, wherein the fresh air current processing channel is separated from the return air current processing channel by the baffle; part of the rotating wheel heat reclaimer is arranged in the fresh air current processing channel, and the other part of the rotating wheel heat reclaimer is arranged in the return air current processing channel; and the vapour compression refrigerating system comprises a gas-liquid separator, a compressor, a condenser, a liquid storage device, a throttling device and an evaporator which are sequentially connected. The air conditioning unit refrigerates in the three modes of full compressor refrigeration, rotating wheel refrigeration assisted by compressor regulating refrigeration and full rotating wheel refrigeration. The refrigerating system is automatically regulated to run in a matched way according to the load of a computer room and outdoor fresh air conditions. No manual intervention is needed, optimum energy efficiency ratio is achieved, and outdoor fresh air is utilized to an utmost extent for providing an indoor space with cold air.

Description

technical field [0001] The invention relates to the technical field of air-conditioning systems, in particular to an integrated combined air-conditioning unit for a computer room and a control method thereof. Background technique [0002] The equipment in the computer room and the base station generates a huge amount of heat during operation. In order to maintain the temperature in the computer room to meet the normal operating temperature of the equipment, the computer room needs to be equipped with air conditioning equipment to provide cooling capacity for year-round operation to cool down the equipment in the computer room. With the rapid development of the information industry and the rapid construction of computer rooms and base stations, the number of computer room air conditioners has increased significantly, and their power consumption and heat dissipation have also continued to increase. The demand for computer room air conditioners has increased accordingly, and th...

Problems solved by technology

When outdoor fresh air is used as the cooling source, the fresh air is often introduced into the computer room after simple filtration. The dust and water vapor in the fresh air, especially sulfur dioxide and other chemical components will pollute the environment in the computer room, and may even cause chemical damage to expensive computer equipment. corrosion

If the incoming fresh air is thoroughly filtered, the unit needs to be equipped with medium-efficiency filters and chemical filters. Among them, chemical filters are very expensive and cannot be cleaned and reused; when chemical filters are used for fresh air treatment, the filter replacement frequency is also high, resulting in very large investment and operating costs of the air conditioning unit
