Description

Technical Field

[0001] The utility model relates to the technical field of evaporative cooling type chillers, in particular to an integral evaporative cooling type chiller. Background Art

[0002] The natural cooling source units currently used in the market usually have two types of natural cooling: air cooling or evaporative cooling. The overall evaporative cooling chiller is more common and can fully recover heat to avoid waste.

[0003] The patent specification with the announcement number CN209295326U discloses an integrated countercurrent evaporative cooling chiller. The high-temperature and high-pressure refrigerant discharged from the compressor enters the countercurrent evaporative condenser for operation. The nozzle in the countercurrent evaporative condenser sprays water downward to keep the interior moist. At the same time, when the fan at the top air outlet is running, the air is forced to enter from the air inlet and blow from bottom to top toward the condensing coil. Before reaching the condensing coil, the air forms convection with the cooling water dripping downward on the condensing coil. Most of the cooling water is cooled and falls into the water reservoir, and a small part of the cooling water evaporates. After the air temperature drops to the wet-bulb temperature, it is blown upward through the condensing coil in countercurrent; a part of the circulating cooling water on the condensing coil evaporates, and its latent heat of evaporation is used to exchange heat with the sensible heat of the refrigerant, taking away a large amount of heat from the refrigerant, which is taken away from the bottom to the top by the air forced to flow by the fan and discharged from the air outlet, thereby greatly reducing the condensation temperature of the refrigerant. After the cooled refrigerant is throttled and reduced in pressure by the expansion valve, it enters the evaporator for evaporation and heat absorption to become refrigerant gas, and then returns to the compressor for compression.

[0004] However, in the implementation of relevant technologies, it was found that the integrated countercurrent evaporative cooling chiller of the above-mentioned design has the following problems: in the prior art, the coolant is cooled by components such as condensing coils, but in actual use, the flow of air is blocked by the internal components of the equipment, resulting in a poor circulation process and a poor air intake speed, thereby failing to perform sufficient cooling. In view of this, an integrated evaporative cooling chiller is provided to overcome the above-mentioned defects. Utility Model Content
