Compared with the shower chamber, the cold water surface cooler has similar air processing capacity, and its advantages are as follows:

A. The equipment has small volume, small room area and easy installation.

B. The water system is relatively simple, because the water circulation can use a closed system, can save the cold water tank and water tank and spray pump; Water and air do not directly contact, avoid air and water mutual pollution, water system water supply greatly reduced;

C. The power consumption of the water transmission system is low. The table cooler of each air conditioner does not need to be set up with a water pump. The resistance loss of the table cooler is all borne by the frozen water pump of the power station.

Cold water surface cooler air treatment has the following disadvantages:

Process of the air is not as diverse as rain water chamber, can only achieve minus enthalpy drop wet (i.e., wet cooling), minus enthalpy wet (i.e., dry cooling) and a part of the roasting temperature (heating) three process, need to add wet, still must up humidifier, not easy to achieve a strict requirements, the relative humidity is this table of air cooler to deal with faults.

Equipment manufacturing process is complex, can not be processed on site, can only be produced by professional factories, on-site assembly; Large metal consumption, generally to consume more non-ferrous metals; The cost is also higher than the drenching chamber, 10000-160000m3 / h eight specifications of table cooler and three row drenching chamber cost comparison, the average is more than 30% higher. No dust removal, deodorization.

In order to eliminate the above shortcomings, increase the heat exchange efficiency, can also be used with drenching surface cooler.

Surface cooler with drenching water, drenching water only for humidification and dust removal. Its processing function can be the same as that of the shower chamber, and it is suitable for the closed cold water system, and the relative humidity requirements are strict and steam humidification cannot be used or steam humidification is not reasonable (for example, there is no steam source or can not provide steam all day). The use of direct evaporation surface cooler can also be processed on the air, to achieve the cooling and drying of the air, which is the method used by small air conditioning units.

Direct evaporation due to the use of refrigeration system evaporator as the air cooler, so the equipment is simple, small volume, small footprint, the initial investment is relatively low; However, the refrigerant has a large pipeline loss and strict sealing is required, so the distance between the evaporator and the freezer should not be pulled too far. Generally, the evaporator of a refrigerator is supplied with a air supply system, which constitutes an integral unit. Direct evaporation type surface cooler is not easy to adjust, it is not easy to maintain strict relative humidity, generally used for relative humidity without strict requirements of the system.
