What is it?
Attached to the condensing unit of an air conditioner is an electrical component called the compressor saver. A compressor saver is a mixing of a relay and a start capacitor. This compressor saver allows the compressor to start up quickly, therefore, it will use less power. It ultimately helps you save money on your energy bill.
Reasons for needing a compressor saver
When your air conditioning unit stars up a compressor has to move a great deal of refrigerant through the unit immediately. The metering device has to run the same amount of refrigerant in a liquid form that a compressor moves in a gaseous state. Both of these actions take a great deal of force and power. The compressor has to be allowed to work in a way that moves gas and liquid efficiently and quickly. The compressor mechanism has to be able to overcome the pressure difference at startup when the expansion valve is a positive shut-off valve.
How does a compressor saver work?
When your air conditioner starts up, the relay is on. Since the relay is continuously on there is energy stored in the capacitor. This energy is needed to power the compressor. Next, the relay then reads the electrical current from the compressor and upon arriving at a certain level, or when the compressor is entirely running, the relay is turned off or rendered out of the circuit. This action makes the start capacitor no longer needed to aid the compressor.
Finally, a hard start kit will allow your compressor to last longer. It may also help your AC unit cool down your home more efficiently. This efficiency will ultimately lead to you having to pay less money on your electric bill. Finally, the possible maintenance cost of a new compressor will be lower because down the road.
