What is a Condensing Unit Heat Recovery Ventilator?

A condensing unit heat recovery ventilator is a device that recovers unused or excess heat from the air and uses it to heat the building or office space. As the name suggests, this device is used for cooling a building. A good example of such a device is an air conditioner unit. The condensing unit works in a similar way except it works by extracting heat from the air. It has a condenser coil that absorbs the heat in the room and passes it through a heat exchanger coil which results in the cooling of the room.

Since air conditioning units are powered by electricity, air conditioners in buildings are also a form of condensing unit. In this case, the heat is derived from the work of condensing air rather than from electricity. Air conditioners are usually controlled manually, so they require no power. In this way, the central air conditioning unit can cool the rooms efficiently.

Air conditioners and their heat recovery ventilators differ in a number of ways. An air conditioner unit is usually cooled by the refrigerant gas such as water or a mixture of water and a compressor; while a heat recovery ventilator recovers heat from the exhaust. The condensing unit is normally situated in the roof, where it extracts heat from the outside air. A heat recovery ventilator operates on the principle of the same principles as an air conditioner unit. Its method of operation is basically the same. In both the units, refrigerant gases are blown into the cylinder, compressed and circulated to the exhaust of the unit. Both these units require electrical power to operate.
