Description
Technical Field
The invention belongs to the technical field of refrigeration machinery, and particularly relates to a super-cooling type efficient evaporative condenser.
Background
The evaporative condensing water chilling unit combines the advantages of water-cooling and air-cooling water chilling units, uses air and circulating water as cooling media, and condenses the high-temperature and high-pressure gas refrigerant discharged by the compressor by using the evaporation latent heat of the circulating cooling water of the evaporative condenser, so that the condensing temperature can be reduced by 4-5 ℃ compared with the water-cooling unit, and the power consumption of a cooling water pump can be saved. Compared with a conventional water cooling system water cooling unit, a cooling water pump and a cooling tower, the evaporative condensation type water cooling unit has the advantages that the refrigeration energy efficiency of the unit can be improved by about 20%; compared with an air cooling unit, the unit refrigeration energy efficiency can be improved by about 60 percent, so that the unit is the host type with the highest energy efficiency ratio in the existing refrigeration and air-conditioning systems, can well overcome the defects of high condensation temperature and low refrigeration energy efficiency of the conventional air cooling and water cooling unit, and is widely applied to the fields of medicines, chemical industry, metallurgy and food and beverage.
The evaporative condenser is used as a core component of an evaporative condensation type water chilling unit, generally adopts a coil pipe type structure, circulating cooling water uniformly covers the outer surface of a coil pipe, a large amount of heat emitted by high-temperature and high-pressure refrigerant vapor in the coil pipe in the condensation process can be efficiently taken away through evaporation of the circulating cooling water, and the heat transfer efficiency is high.
The condensation temperature of the conventional evaporation condensation type water chilling unit in the prior art is low, the heat exchange pipe diameter of the evaporation type condenser is relatively thick so as to facilitate liquid drainage, and the temperature of a water film on the surface of the heat exchanger, which is closer to the refrigerant outlet, is higher under the influence of the special structure of the evaporation type condenser, so that the supercooling degree of high-pressure liquid at the outlet of the evaporation type condenser is approximately zero. When the high-pressure saturated liquid from the liquid reservoir passes through the drying filter, the stop valve, the electromagnetic valve and the high-pressure liquid pipe, local resistance and on-way resistance cannot be avoided, so that the saturated liquid generates a flash evaporation phenomenon, and part of the saturated liquid is changed into saturated gas. Because the volume of the saturated gas is about 40 times of that of the saturated liquid, once a gas refrigerant carried in the high-pressure liquid enters the throttling device, the flow of the refrigerant is seriously influenced, so that the evaporation temperature of a unit is reduced, and the refrigerating capacity and the refrigerating energy efficiency are seriously attenuated; meanwhile, the flash evaporation gas can also cause unstable flow of the liquid refrigerant supplied to the evaporator from the throttling device, even intermittent liquid supply is generated, and great risk is generated on unit performance and compressor operation reliability, so that the unit stability is poor.
Prior art ZL201711443621.7, name: the evaporative condenser comprises a water circulation component, wherein the tail end of a water pipeline is provided with a main water pipe and an auxiliary water pipe, and when the coil is cooled, a plurality of auxiliary water pipes effectively cool each part of the coil through a plurality of auxiliary spray heads. Although the problem that the temperature of spray cooling water is higher and higher from top to bottom is solved, when the refrigerant flows out from the bottom of the heat exchanger, the temperature of a water film close to the surface of the heat exchanger at the refrigerant outlet is high, and the supercooling degree of the refrigerant at the outlet of the evaporative condenser is still low.
