Sometimes referred to as heat pumps, reverse cycle air conditioning systems utilize refrigeration and reverse refrigeration cycles to cool and warm a household respectively.
The reverse refrigeration cycle involves using a compressor to pump refrigerant into a condenser. The compression process warms up the refrigerant, which, in turn, warms up the air. The hot air then gets blown into the household via a fan. The refrigerant then flows into an evaporator for cooling before it gets pumped back into the condenser for recycling.
When the cycle gets reversed, the air conditioning system provides warm air for the home instead of cold air.
These types of air conditioning systems also include air filters as well dehumidifiers, and they are reputed for their energy efficiency as well as all season air conditioning throughout the year.
Types of reverse cycle air conditioning
Split reverse cycle air conditioning systems
The design of this kind of reverse air conditioner is composed of two main parts. The first component is comprised of the evaporator and the condenser and gets located inside the home. The second component comprises of the compressor and gets installed on the outside of the home.
Piping connects both parts (in and out) through the wall, and the piping is also responsible for the to and fro flowing of the refrigerant.
Standard split, reverse cycle air conditioning systems vary in heat output and thus they often get recommended for use in rooms that do not exceed 100 square meters. However, multi-split reverse cycle air conditioning systems provide better heating than standard models, and hence they are recommended for larger rooms that do not exceed 200 square meters. Multi-split a/c systems can get identified as having a single outdoor component connected to multiple indoor units.
Ducted reverse cycle air conditioning systems
These types of air conditioners get characterized by having various ducts connecting individual rooms of the house to a single central unit. Though these systems are quite expensive due to the need to install individual ducts for each room, they are quite efficient because they have the capacity to provide adequate air condition for rooms as large as 80 square meters.
Wall mounted, and window mounted reverse cycle air conditioning systems
Unlike the ducted version, these types of a/c systems are the most affordable and easiest to install because all the components get designed as a single functioning unit.
Hence, for installation, the single unit only needs to get attached to a window or a hole in the wall. For efficient use, this type of a/c system gets recommended for rooms that are no larger than 70 square meters.
Cassettes reverse cycle air conditioning systems
These types of reverse cycle air conditioning systems resemble the split system with the only difference being that the evaporator and condenser (indoor unit in split system) get placed on the roof of the house.
The cassette systems are much stronger than the other systems listed above, and thus they often get installed in commercial and industrial buildings.
