8. FUNCTION
8-1. Motion Explanation
8-1-1. Heating
Heating operation begins with the refrigerant pump down cycle to move refrigerant into the heating circuit of the
system. Simultaneously, gas burner ignition is initiated for a period of about 1 minute.
When the refrigerant transport period is completed, refrigerant is contained within the heating circuit tubing and
retained there by the 2 check valves. The refrigerant pump down circuit condition is established by the reversing
valve set to the heating position and the ON/OFF valve, V1, is closed.
Upon completion of the pump down phase, the ON/OFF valve is opened for normal heating operation.
Cooling heat transfer tubing in the outdoor section is blocked from refrigerant flow by check valves during the
heating cycle.
Heating circuit refrigerant tubing is in contact with the exterior wall of the aluminum heat exchanger above the gas
burner. Heated refrigerant is circulated from the outdoor heat exchanger tubing to the indoor heat transfer tubing
by operation of the compressor. Controls maintain refrigerant temperature to a point above the saturation temper-
ature and so the temperature is circulated as a gas.
Refrigerant flow is through the ON/OFF valve, V2, under stable conditions to provide for low power operation.
Low power operation is initiated (V2 opens) when thermistor-1 senses the temperature of equalization at 263 psig
(18.5 kg/cm
2
).
8-1-2. Cooling
Identical to operation for a typical ductless split air conditioner (heat pump).
