Definitions

  • the present invention relates generally to an air conditioner. More particularly, this invention relates to an air conditioner which is capable of reducing its standby power consumption.
  • An air conditioner involves three major components i.e., a compressor, an outdoor heat exchanger (also known as a condenser in cooling mode), an indoor heat exchanger (also known as an evaporator in cooling mode) and an expansionary device such as capillary tube to compose a refrigerating cycle.
  • a compressor also known as a condenser in cooling mode
  • an indoor heat exchanger also known as an evaporator in cooling mode
  • an expansionary device such as capillary tube to compose a refrigerating cycle.
  • split-type air conditioner is the most typical air conditioning system installed in the residential and commercial applications.
  • Split-type air conditioner comprises of at least an indoor unit and an outdoor unit.
  • the outdoor unit is connected via refrigerant piping to one (typically known as single-split) or more (typically known as multi-split) indoor units.
  • Split-type air conditioner requires electrical power to be supplied to both indoor and outdoor unit. The electrical power connections are typically made either via a terminal block of the indoor unit or via a terminal block of the outdoor unit.
  • split-type air conditioner endures higher consumption of standby power due to, for example the constant communication between the indoor and the outdoor unit.
  • standby power is defined as the energy consumed by appliances when they are not performing their main functions or when they are switched off by remote controller.

It is designed to keep the bottom part of the compressor where lubricant is accumulated at a temperature higher than the coldest part of the system.
  • the reason that the crankcase heater imposing higher standby power consumption is that the crankcase heater is normally on even during the off cycle to warm the refrigerant, to reduce refrigerant migration, and to ensure proper compressor lubrication. If the air conditioner unit is started up without warming the crankcase, the lubricant and refrigerant will be pumped out of compressor which could damage or severely reduce the operational life of the compressor.
