Air Conditioning

Common air conditioners are regulated only by thermostat. When the chosen temperature is reached, the appliance turns itself off. If it is exceeded, it switches itself on again. In units with inverter technology the number of revolutions of the compressor is regulated steplessly, i. e. the unit powers down slowly and also reverts to adopting power gradually. The room temperature can be maintained even more uniformly, moreover appliances with inverter technology consume notably less energy.

The refrigerant is a fixed component of any climate system. As a heat carrier it transports, when cooling, the space heating from the inside to the outside unit and, when heating, the other way round. Modern air conditioners contain the CFC-free refrigerants R 410 A oder R 407 C. R 410 A increase in addition the level of efficiency of air conditioners and permits notably compact designs. The refrigerant circulates in a closed circuit and, therefore, won´t escape. When installing, a qualified air conditioning fitter fills your air conditioner competently with refrigerant and examines the density of the system. If the unit should someday have to be dismounted, the installer draws the refrigerant into recycling refrigerant bottles for the professional disposal.

The split air conditioner comprises of two parts: the outdoor unit and the indoor unit. The outdoor unit, fitted outside the room, houses components like the compressor, condenser and expansion valve. The indoor unit comprises the evaporator or cooling coil and the cooling fan. Further, the present day split units have aesthetic looks and add to the beauty of the room. The split air conditioner can be used to cool or heat one or more rooms simultaneously. One outside unit can be connected with several inside units (split or multisplit).

A heat pump is an additional option of high-grade climate-systems. These climate systems are also capable to heat. A heat pump inverts the principle of the refrigeration. It is a device that moves heat from one location at a lower temperature to another location at a higher temperature using mechanical work or a high-temperature heat source. Heat pumps are an adequate and economical alternative to conventional heatings.

The efficiency indicates how much cooling or heat energy the climate system gets of the applied electrical energy. The ‘Efficiency’ of air source heat pumps is measured by the coefficient of performance (COP). Units of the energy class A have, for example a COP of at least 3,2; this signifies, that of 1 kW electric power can be generated not less than 3,2 kW refrigeration and accordingly heat capacity. When using part-load operational range, the COP amounts actually 4 to 5, as the power consumption is proportionally to the output power even lower.
