Air Conditioning

The basic principle of air conditioning: to absorb energy in one place and release it in another place

The process requires an indoor unit, an outdoor unit and copper piping to connect both. Through the piping the refrigerant flows from one unit to another. It is the refrigerant that absorbs the energy in one unit and releases it in the other.

Cooling mode

1 Indoor unit
A fan blows the hot indoor air over a heat exchanging coil through which cold refrigerant flows. The cold refrigerant absorbs the heat from the air and cooled air is blown into the room.

2 Copper piping
The refrigerant circulates through the units and the piping and takes the heat from the indoor unit to the outdoor unit.

3 Outdoor unit
Through compression, the refrigerant gas is heated and its boiling point increases. In the outdoor unit the obtained heat throught compression is released to the outdoor air by means of a fan which blows the outdoor air over a heat exchanging coil.

4 Refrigerant
The liquid refrigerant flows back to the indoor unit.

5 Indoor unit
Back in the indoor unit, the refrigerant is decompressed and thus enabled to extract heat form the indoor air.

Heat pumps: Using air conditioners to heat

Heat pumps are an integral part of air conditioning technology. Heat pumps transfer heat from one environment to another via refrigerant.

In cooling mode, heat pumps transfer the heat in an enclosed area (room, industrial process) to the outside air, resulting in a cooling of the area in question. This is the role that heat pumps have in common with refrigeration and air conditioning systems. Heat pumps, however, also allow this process to be reversed. They can pump heat extracted from the outside air indoors, allowing indoor environments to be heated as well as cooled using the same technology.

Heat pump efficiency

Heat pumps offer numerous advantages as a heating solution. The same systems used to cool can also be used to heat, resulting in less initial investment and simplicity in operation and maintenance. They / Heat pumps also have an important advantage in the area of efficiency. Unlike fossil-fuel based heating systems, heat pumps extract available heat from the outside air. Heat pumps offer efficiency gains on the order of 3:1 and higher, compared to electrical heating. Thus for every unit of energy consumed by the heat pump, three or more units of heat are gained.

Heat pump comfort

Heat pumps in combination with modern inverter technology offer unparalleled indoor heating comfort and process efficiency. Heat pumps can extract heat energy from the outside air even on the coldest days of winter. Heat pump systems are capable of meeting exacting industrial heating and cooling requirements as well as of providing comfortable and efficient indoor heating.
