Description

Novel-structure efficient energy-saving evaporation integrated water chilling unit

Technical Field

The utility model relates to the technical field of counter-flow evaporative condensers, in particular to a novel-structure efficient energy-saving evaporative integrated water chilling unit.

Background

The evaporative condenser, namely evaporative cooling, is a heat exchange device for cooling a refrigeration house, and is formed by combining components such as a fan, a condensing coil, heat exchange plates, a box body and the like, and the principle is as follows: the superheated high-pressure refrigerant gas discharged from the compressor in the refrigerating system passes through the condensing calandria in the evaporative condenser, so that the high-temperature gaseous refrigerant exchanges heat with spray water and air outside the calandria. The gaseous refrigerant is gradually condensed into liquid refrigerant from top to bottom after entering the calandria from the upper opening. The super strong wind power of the matched induced draft fan enables the spray water to completely and uniformly cover the surface of the coil pipe, and the water is used for greatly improving the heat exchange effect by wind force. Part of the spray water with the temperature increased becomes gaseous, a great amount of heat is taken away by wind potential by utilizing the vaporization latent heat of the water, water drops in the hot air are caught by the high-efficiency dehydrator, and the water drops and the rest water which absorbs the heat are scattered into the heat exchange layer of the PVC spray water sheet, cooled by the flowing air, the temperature is reduced, enter the water tank, and are continuously circulated by the circulating water pump. The water evaporated into the air is automatically replenished by the water level regulator.

The evaporator is an important part in four refrigeration parts, low-temperature condensed liquid is subjected to heat exchange with the outside air through the evaporator, and the air absorbs heat in a gasification way, so that the refrigeration effect is achieved, and the evaporator mainly comprises a heating chamber and an evaporating chamber. The heating chamber provides heat required for evaporation to the liquid, causing the liquid to boil and evaporate; the evaporating chamber makes the gas-liquid phase completely separate.

At present, a plurality of manufacturers develop and manufacture the evaporative cooling integrated water chilling unit in the market, but the bottleneck problem of the evaporative cooling integrated water chilling unit is not overcome, and the existing analysis is as follows:

as shown in fig. 1, in the running state of the refrigerator, p1+.35 ℃ corresponds to pressure, p2+.30 ℃ corresponds to pressure, p3=reservoir saturation pressure; in a shutdown state with the ambient temperature of 40 ℃, the saturated pressure of P3=40 ℃ is reduced gradually along with the cooling of evaporative cooling after the startup operation, in order to reduce the pressure of the liquid storage device, a balance pipe is arranged between the liquid storage device and the evaporative cooling air inlet pipe, the flash gas generated by the influence of the ambient temperature of the liquid storage device can flow to the evaporative cooling, so that the pressure P3 and P3 are approximately equal to P1 of the liquid storage device, even if the P2 is smaller than P3, a section of hydrostatic column H is required to be naturally produced, P2+H is more than or equal to P3, so that the liquid condensed by the evaporative cooling can flow to the liquid storage device, thereby meeting the refrigeration cycle, and in terms of R134a (R507, R410a and R22) refrigerant, the hydrostatic column H=1500 mm, the height H2 of the liquid storage device=700 mm, and the lowest height of the falling liquid pipe is 1500+700=2200 mm; the height limit height of the evaporative cooling integrated water chilling unit is less than 3000mm, otherwise transportation is limited; under these constraints, the evaporative cold drop tubes currently on the market have difficulty meeting a liquid drop height of 2200 mm.
