Abstract

A water source heat pump system having a plurality of zone air conditioning units, each unit adapted for selectively heating or cooling a zone independent of other units, each air conditioning unit having an air-to-refrigerant heat exchanger, a water-to-refrigerant heat exchanger of the type having a water contact coil disposed within a housing, a refrigerant compressor, and refrigerant control means operable to selectively cause the air-to-refrigerant exchanger to act as a refrigerant evaporator or condenser and the water-to-refrigerant heat exchanger to act as a refrigerant condenser or evaporator, the water-to-refrigerant heat exchanger and the air-to-refrigerant heat exchanger utilizing thermostat control means to control the operation of the air conditioning unit so as to prevent freezing of water in the water-to-refrigerant heat exchanger during the heating cycle and prevent frosting or freezing of condensate on the air side of the air-to-refrigerant exchanger during the cooling cycle.
