ODT means Outside Thermostat. ODT is really a thermostat Positioned outdoors the creating made use of to manage a secondary heating system when the outside temperature fall beneath the setpoint.
SEER stands for Seasonal Energy Effectiveness Ratio. SEER indicates the Strength efficiency of the air conditioner in cooling. It involves the air conditioner to generally be tested below an setting that resemble the cooling year. The upper the SEER quantity, the bigger the efficiency.
IFR means Indoor Enthusiast Relay. IFR is used to control the operation of your indoor admirer motor. Upon energized, it will physically lid and shut the circuit therefore allowing for electricity to pass through and begin the indoor enthusiast motor.
It may be any form together with finned-tube warmth exchanger which is usually located in household break up air conditioners or shell-and-tube warmth exchanger that is extra usually present in drinking water-cooled chiller.
LPS means Low Force Swap. LPS is usually located in compressor and refrigeration system. In the event the cooling demand is too minimal, the refrigerant doesn’t take in plenty of warmth.
OAD means Outside Air Duct. OAD is usually present in duct structure drawings, especially for the air flow system. A duct measurement may be published correct beside OAD to point the outside air duct sizing. It is additionally frequent to have the OAD word physically painted over the outside air duct.
