Abstract

Cooling apparatus providing two independent heat exchangers (18, 20) serially arranged with respect to a heat flow (42), each heat exchanger being connected to a respective independent chiller (32, 34). The apparatus incorporates an element of redundancy in order to effect an increase in operational efficiency, by being switchable between a first operation mode in which both chillers operate in a free cooling mode and a second operation mode in which a first chiller operates in a free cooling mode and a second chiller operates in a forced cooling mode.

Description

FIELD OF THE INVENTION

[0001] This invention relates to cooling equipment, e.g. for air conditioners, electrical appliances or the like, in which fluid coolant is circulated between a absorbing region where it absorbs energy from the surrounding environment and a cooling region where it emits energy to the surrounding environment.BACKGROUND OF THE INVENTION

[0002] Electrical appliances, e.g. televisions, PCs, servers and the like, emit heating during operation. In the case of information technology (IT) equipment it is often necessary for operation to be continuous. Problems, e.g. malfunction, may occur if the equipment overheats, so it is important to control the temperature of the surrounding environment.

[0003] Air conditioning may be used to control the temperature of a space, e.g. room, warehouse or the like, that contained heat generating equipment. Conventional air conditioning apparatus operates to cool air, which is subsequently circulated in the space to control the temperature....
