Abstract

The invention provides an energy-saving water chilling unit and a water chilling control method for the same. The water chilling control method for the water chilling unit includes the following steps: acquiring temperature value, water pressure and working medium flow; according to the temperature value, the water pressure and the working medium flow, judging whether the energy-saving water chilling unit meets chilling-switching conditions; and if yes, switching the energy-saving water chilling unit to a natural chilling mode or a compressor chilling mode. By means of the energy-saving water chilling unit and the water chilling control method for the same, an outdoor natural cold source can be utilized to chill a device when the outdoor temperature is low in the transition season and winter, the natural chilling mode and the compressor chilling mode can be flexibly switched, the problem on how to dissipate the heat of a computer room is effectively solved, the efficiency of a cold source device is increased, moreover, energy consumption is low, the reliability is high, and the service life is long.

Description

technical field [0001] The present invention relates to water-cooling and refrigeration technology, in particular to the water-cooling and refrigeration technology for data center computer rooms, and in particular to an energy-saving water-cooled chiller and a water-cooling control method for the chiller. Background technique [0002] With the rapid growth of data business demand and the rapid development of IT technology, the power density of equipment in the data center computer room is getting higher and higher. In order to ensure the normal operation of IT equipment around the clock, the data center computer room needs to be equipped with special all-weather cooling equipment. To maintain the environment in the computer room to ensure the normal operation of IT equipment. [0003] Currently, there are two main cooling methods for data center computer rooms: [0004] 1) Traditional air-cooled and water-cooled cooling methods: Although this cooling method meets the temper...
