Point refrigeration system of machine room

The invention relates to the field of refrigeration equipment, and aims at providing a point refrigeration system of a machine room. The point refrigeration system of the machine room achieves single-point refrigeration and is high in efficiency, low in energy consumption, simple in structure and easy and convenient to operate. The point refrigeration system of the machine room comprises equipmentcabinets, air conditioner cabinets, power distribution cabinets and dehumidification cabinets. Closed space is formed by the equipment cabinets, the air conditioner cabinets, the power distribution cabinets and the dehumidification cabinets. An inner cycle is formed by the air conditioner cabinets and the equipment cabinets in the closed space. The air conditioner cabinets provide cold sources for the adjacent equipment cabinets. The power distribution cabinets supply power to the equipment. The dehumidification cabinets dehumidify the closed space. 本发明机房点制冷系统涉及制冷设备领域。其目的是为了提供种单点制冷、效率高、能耗低、结构简单、操作简便的机房点制冷系统。本发明机房点制冷系
