A water evaporation refrigeration system

Abstract

The invention discloses a water evaporative refrigeration system. Refrigeration is conducted according to the one-to-one correspondence relationship between the boiling point temperature of water andthe pressure. The water evaporative refrigeration system is mainly composed of an evaporator, a condenser and a negative pressure pumping device; the evaporator is mainly composed of a plurality of unit negative pressure cavities, an air supplying fan and an air outlet. Treated air flows in an air flue among all the unit negative pressure cavities, the interiors of the cavities can be pumped to bein different pressures according to the actual refrigeration temperature, and thus liquid water evaporates in the cavities to absorb the heat of the processed air; the negative pressure pumping device pumps out water vapor evaporated in the evaporator in time and exhausts the water vapor to the condenser, the set negative pressure in the negative pressure cavities of the evaporator can be maintained, the corresponding pressure when the water boiling point in the cavities of the condenser is equal to the environment temperature can be ensured, a valve located on a small pipeline a outside theevaporator can adjust the circulating water flow of the system, and thus the purpose of adjusting the refrigeration amount of the system is achieved indirectly.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration devices, and in particular relates to a water evaporation refrigeration system. Background technique [0002] Under the background of the country's continuous promotion of energy conservation and emission reduction, water evaporative cooling technology has been applied in the field of air conditioning and ventilation. However, because the current evaporative cooling air-conditioning technology is restricted by environmental parameters, the temperature of the cold water or cold air produced by it fluctuates with the outdoor climate parameters, which makes the application of water evaporative cooling technology have certain limitations. [0003] The existing air-conditioning system is mainly divided into two types: packing type and non-filling type. The circulating water volume with packing is small and the air volume is large, which is suitable for cooling fans; the water...
