With over 45 years of experience in the HVAC and electrical industries, Jack Lehr is your single source for comprehensive split AC and packaged HVAC services. The refrigeration cycle, another common HVAC term, refers to the compressor, condenser, and evaporator coils located in your HVAC system. These units still feature the outdoor unit. In this article we take a look at how an inverter works to convert direct current (DC) into Alternating current (AC). A split-system air conditioner splits the hot side from the cold side of the system, as in the diagram below. Compression of refrigerant produces heat. There will also be a unit located indoors, often (though not always) attached to your furnace. This air is circulated through the system and will eventually blow over the evaporator coil—housed in the indoor unit of a split system—where it will rapidly cool before being put back into your home via the supply vents.

The difference with a mini-split system is that they are separated into two different, distant components, one being outdoors and one being indoors.

Non-inverter type air-conditioner. And duct leakage is a real problem with central air conditioners. Explanation: Every air conditioner (also pronounced as AC, A/C or Air Cooler in certain regions of the world) has got a compressor inside it.It works to compress and pump the refrigerant gas. On the exterior of the home is the compressor/condenser, which maintains the optimum rate of the refrigerant’s flow as well as increases the pressure of the refrigerant gas through compression. The first modern air conditioning system was developed in 1902 by a young electrical engineer named Willis Haviland Carrier.
