China Precision Air Conditioner Manufacturers, Suppliers, Factory

Guangdong Yili High-tech Co., Ltd., a subsidiary of Shangyu CPSY Group, is a high-tech precision air conditioning company that designs, manufactures, and sells semi-customized computer room air conditioning equipment. Its products cover commercial and non-commercial uses. As a global leader in computer room precision air conditioning systems One of the suppliers in the field, Shangyu CPSY specializes in a series of products: AM & EM series room-level precision air conditioners, SP series computer room inter-column air conditioners, SPR rack-type special precision air conditioners and other products. The products manufactured have passed strict Run tests to meet standards, products are designed with quality, energy efficiency, and reliability in mind. With operations around the world and continuous accumulation of capabilities in developing innovations and solutions, the Group has become a global leader in computer room air-conditioning environments.

Precision air conditioning is a type of air conditioning equipment designed for special environments. It has the characteristics of high precision, high reliability, low noise, high efficiency and energy saving. It is installed side by side with the server cabinet. The horizontal air supply method is from the cold aisle in the front and the hot aisle return air in the rear. This solves the problems of mixing and short circuiting of hot and cold air flow in conventional air conditioners, thus ensuring uniform temperature of the server cabinet and eliminating localized airflow. Hot spots, the circulating air volume circulates in a closed cycle between hot and cold aisles and inter-column air conditioners. It is especially suitable for micro-module systems with closed hot and cold aisles. It is equipped with an advanced controller to control the air volume and cooling output on demand, and can accurately control the temperature and temperature of the computer room. Humidity can effectively reduce overall energy consumption on the basis of ensuring effective cooling. It uses advanced control technology and efficient refrigeration technology to provide a constant temperature, constant humidity, and clean air environment. It is suitable for various data centers, communication rooms, laboratories and other important places.

As we all know, the load load (w/m2) in computer room applications continues to rise, mainly caused by the increase in data center rack load, which ultimately results in a relatively high heat load density. This requires the air conditioning system to have better performance while occupying as little space as possible, thereby providing more space for equipment in the computer room. The precision air conditioner used on servers (horizontal air supply type) has a surrounding air intake and wind split system, which can meet the cooling standards of the new generation of computer rooms and server centers. With extremely high refrigeration density (up to 25KW on a surface of 0.8mm2). It adopts a modular design, includes an adaptive logic system, and can be managed through the network. It is the best partner for server architecture and high-density equipment, and is ideal for telephone exchanges, data centers, Internet, service centers and high-density buildings. ideal refrigeration system.

Although the initial investment of precision air conditioners is basically much higher than that of ordinary air conditioners, the annual operating cost of ordinary air conditioners is $243/per sensible cooling capacity higher than that of precision air conditioners. This is consistent with the principle generally recognized by the industry, that is, the cooling capacity of 3 refrigeration tons of ordinary air conditioners is equivalent to the refrigeration capacity of 2 refrigeration tons of precision air conditioners.

To sum up, there are significant differences in product design, application scenarios, functions and performance between precision air conditioners for computer rooms and home comfort air conditioners, which need to be selected and used according to specific needs.
