Problems solved by technology
[0005] Existing methods to obtain PUE can only be obtained during the operation and maintenance of the data center based on the actual measured IT load and the total load of the Internet data center, so it is impossible to evaluate the energy efficiency of the air-conditioning system of the water-cooled chiller in the data center at the design stage , resulting in the inability to optimize the energy consumption structure of the water-cooled chiller air-conditioning system in time during the design process of the water-cooled chiller air-conditioning system

The invention relates to the technical field of energy planning, and discloses a method for predicting a refrigeration load coefficient of a water-cooling water chilling unit air conditioning system. Comprising the steps that the energy consumption estimated value of a cooling tower is obtained, the energy consumption estimated value of a water chilling unit is obtained, the energy consumption estimated value of a water pump is obtained, the energy consumption estimated value of an air conditioner tail end fan is obtained, and the energy consumption estimated value of water treatment equipment is obtained; according to the energy consumption estimated value of the cooling tower, the energy consumption estimated value of the water chilling unit, the energy consumption estimated value of the water pump, the energy consumption estimated value of the air conditioner tail end fan and the energy consumption estimated value of the water treatment equipment, the refrigeration load coefficient of the water-cooling water chilling unit air conditioning system is predicted; and predicting the refrigeration load coefficient of the water-cooling water chilling unit air conditioning system according to the refrigeration load coefficient. Therefore, the energy use efficiency of the water-cooling water chilling unit air-conditioning system in the data center can be evaluated. The invention further discloses a device for predicting the refrigeration load coefficient of the water-cooling water chilling unit air conditioning system and electronic equipment.
Description
technical field [0001] The present application relates to the technical field of energy planning, for example, to a method, device and electronic equipment for predicting the cooling load factor of a water-cooled chiller air-conditioning system. Background technique [0002] Power Usage Effectiveness (PUE), that is, the ratio of the total energy consumed by the Internet data center (total load) to the energy consumed by IT (Internet Technology, Internet technology) equipment (IT load), is a measure of the power usage of the data center. indicators of efficiency. The total energy consumed by the Internet data center includes the energy consumed by IT equipment and the energy consumed by the power supply and distribution system. The closer the value of energy use efficiency is to 1, the better the energy use efficiency of the data center is. [0003] In the Internet data center, in order to ensure the normal operation of the Internet data center equipment and avoid equipment ...
