Methods of Free Cooling

Assuming that the adjustment can advance chargeless cooling, there are three means to use chargeless cooling:

Strainer Cycle - The cooling belfry baptize can be anon affiliated into the breeze through the algid baptize circuit. If the cooling belfry is accessible again a strainer is appropriate to annihilate any bits that could accrue aural the tower. The amount accumulation are associated with the bound use of the baptize alarming activity There is an added accident of bane application this method.

Plate and Frame Calefaction exchanger - A calefaction exchanger, will alteration calefaction anon from the algid baptize bend to the cooling belfry loop. The exchanger keeps the cooling belfry baptize abstracted from the coolant abounding through the cooling coils. The alarming baptize is appropriately pre-cooled. An activity accumulation is due bargain alarming loading and appropriately a abridgement in activity consumption. There is an access in amount due to the pump charge to atone for the burden differences.

Algidity Migration - A valve adjustment aural the baptize alarming opens a absolute aisle amid the condenser and the evaporator. The almost balmy aqueous in the alarming bend vaporizes the refrigerant, and the activity is agitated anon to the condenser, area it is cooled and abridged by the baptize from the cooling tower.4 This adjustment is apprenticed by the abstraction that the refrigerant tends to move appear the coldest point in a algidity circuit. The amount accumulation associated with this adjustment are due to the compressor’s inactivity, back the blower, fans, and pumps are all operational5
