Problems solved by technology

[0019] Where building management operators typically seek to replace or retrofit existing open-loop heat exchangers to eliminate the current cooling system's risk of breeding airborne Legionella pneumophila, including pre-coolers and closed-loop heat exchangers The problem of reduced cooling capacity of heat exchanger equipment is a critical issue
In a large number of existing installations, the physical space available on the roof is limited and it is not possible to replace the existing open loop heat exchanger with a larger closed loop heat exchanger installation
Additionally, the capital cost of such equipment increases significantly as the physical size increases

Embodiment Construction

[0077] refer to figure 1 , provides a schematic diagram of a conventional cooling system installed with a cooling tower. Such systems are typically used in larger buildings with large spaces to be cooled, and are usually set up so that most of the cooling system is located in the building basement and the cooling tower is located on the building's roof.

[0078] exist figure 1 In the example, a building 10 has an installed cooling system comprising a refrigerant gas loop 12 passing through a condenser 14 and an evaporator 16 . Refrigerant gas flow through loop 12 is driven by a compressor 18 and regulated by expansion valve 20 . The air within the building 10 is generally cooled by drawing air through ducts in which part of the cold water loop 22 resides. This process achieves cooling of the air within the building 10 .

[0079] The refrigerant gas is passed through a condenser 14 for the purpose of cooling the refrigerant gas. Typically, in large buildings, refrigerant g...

Abstract

The invention provides a fluid cooling heat exchanger including: a primary heat exchanger including a closed circuit for circulating cooling fluid; an air cooler located upstream of the primary heat exchanger; a fan arrangement operating to force air through the air cooler and the primary heat exchanger; and a liquid dispenser which operates to dispense liquid into the forced air. The liquid dispenser is located downstream of the air cooler and upstream from the primary heat exchanger. The air cooler includes a moisture absorbent material that is, in use, maintained moist such that air forced through the cooler is cooled by the action of evaporation prior to being forced over a portion of the closed circuit in the primary heat exchanger.

Description

technical field [0001] The systems and methods of the present invention relate generally to cooling of air, and more particularly to a system and method of cooling air within the system including a heat exchange device for effectuating heat transfer from a cooling fluid . The invention is particularly suitable for use in cooling systems of larger volumes of air, such as are required in the case of air cooling in large office buildings or the like. Background technique [0002] Some form of heating and / or cooling of the area where people are is often required to keep the area at a suitable temperature. In some cases, regulations or protocols require an area or premises to be maintained within a certain temperature range. [0003] As a result, heating and cooling systems arose early and are present in most modern buildings to maintain temperatures within predetermined temperature ranges in these buildings. [0004] The heating and cooling of large areas, such as office buil...
