Enthalpy difference optimizing method for cooling device

Abstract

The invention discloses an enthalpy difference optimizing method for a cooling device, which comprises the steps of: comparing an actual enthalpy of water evaporation air conditioner outdoor moist air with a maximum enthalpy allowed in a dry-bulb temperature and relative humidity range needing being controlled by a water evaporation air conditioner regulation region, namely, a target region; if the actual enthalpy is less than the maximum enthalpy of the target region, starting water evaporation refrigeration by a control system of a water evaporation air conditioner; otherwise, stopping the water evaporation refrigeration by the control system of the water evaporation air condition, and starting acting refrigeration by a compressor. According to the enthalpy difference optimizing method provided by the invention, the utilization of the original enthalpy difference air conditioner system is greatly increased, namely, the total comprehensive energy-saving efficiency is increased; and under the condition of greatly developing an energy-saving and emission-reducing technology in current, the immeasurable importance is developed.

Description

technical field [0001] The invention relates to a control method for a device that uses the principle of water evaporation cooling to lower the temperature, especially a method for judging whether low-enthalpy humid air can be used for cooling when cooling a certain area. Specifically, it is a method for optimizing enthalpy difference for a cooling device. [0002] The names of cooling devices include (but are not limited to) water evaporative air conditioners, equal-enthalpy air conditioners, and enthalpy-difference air-conditioning systems. The following only uses enthalpy-difference air-conditioning systems as the elaboration object for devices that use the principle of water evaporative cooling to reduce temperature. Background technique [0003] With the development of society, saving energy has become a social consensus. In order to save power resources, many devices use the principle of direct water evaporative cooling to reduce the air temperature, such as the intel...
