摘要

An air conditioning system for heating and cooling a plurality of peripheral zones and a central zone within a building, comprising a conductor for circulating a heat transfer fluid to said peripheral zones, a reverse cycle refrigeration units in said peripheral zones having a first heat exchanger element disposed in thermal transfer relation with the circulating fluid through said conduit, and a second heat exchanger element disposed in thermal transfer relation with the air of its corresponding zone, being supplied to said first and second heat exchanger elements a common refrigerant and being communicated with each other operatively, so that such elements can operate respectively as evaporator of the refrigerant and as condenser of the refrigerant or, respectively, as condenser of the refrigerant and evaporator of the refrigerant, being operable theseunits in a cycle to transfer heat from said heat transfer fluid to the air of its corresponding zone, and, in the other operating cycle to transfer heat from air to said heat transfer fluid, constituent means of heat source connected to said heat transfer fluid. Said conduit for adding heat to the heat transfer fluid when required, a refrigeration unit for cooling the transfer fluid when required, and a second refrigeration unit providing a heat transfer relationship between said conduit and said central region of the heat transfer fluid. Mentioned building, said central zone being within a part of the building where there is no sensibly heat transmission through the walls, to lose or gain heat, such that said central zone only requires cooling due to internal heat gains within of said central zone, said second refrigeration unit comprising an apparatus the refrigeration unit is designed to operate exclusively as a refrigeration unit to transfer heat from said central zone to said thermal transfer fluid.
