YCAA-H Cooling Mode

Low pressure liquid refrigerant enters the cooler

(Evaporator) and is evaporated and superheated by the

heat energy absorbed from the chilled water passing

through the cooler plates. Low pressure vapour passes

through the four way valve and accumulator before

entering the compressor where pressure and superheat

are increased. The superheated refrigerant vapour

again passes through the four way valve and enters the

air cooled condenser coil. Heat is rejected via air cooled

condenser coil and fans. The fully condensed and

subcooled liquid refrigerant then enters the expansion

valve where pressure reduction and further cooling

takes place before returning to the cooler.

YCAA-H Heat Pump Mode

Liquid refrigerant enters the ambient coils and is fully

evaporated and superheated by the energy absorbed

from the ambient air. Low pressure superheated

refrigerant vapour passes through the four way valve and

accumulator and enters the compressor, where pressure

and superheat are increased. High pressure superheated

refrigerant vapour again passes through the four way

valve and enters the cooler where heat is rejected to the

water circulating through the plates. The high pressure

liquid refrigerant, leaving the cooler, enters the

thermostatic expansion valves where the refrigerant

pressure is reduced and subsequently cooled before

returning to the ambient coils.

When ice builds up on the ambient coils defrost is

initiated by operating the machine in a cooling mode

without the fans running.
