Responsibility for Energy and Environment Hovalwerk AG / Nov-14Heat Pumps10 Principle of a Heat Pump Important terms: COP = Coefficient of Performance Ratio of heat output and electrical input SEER = Seasonal Energy Efficiency Ratio Ratio of heat energy output and electrical energy input per year

Responsibility for Energy and Environment Hovalwerk AG / Nov-14Heat Pumps11 Working Principle 100 % 25 % 75 %

Responsibility for Energy and Environment Hovalwerk AG / Nov-14Heat Pumps12 Heat Pump Operating Principle 1. The heat gain takes place in the evaporator. The liquid evaporates even in sub-zero temperatures, thus storing the recovered energy. 2. The volume of the refrigerant, now in gaseous form, is then drawn in an reduced by the compressor. When the refrigerant is compressed, the pressure increases significantly, thus also increasing the temperature of the refrigerant. 3. Within the closed circuit, the hot refrigerant flows on to the liquefier – a heat exchanger in which the recovered environmental heat is transferred to the heat system. 4. Thanks to the cooling process, the refrigerant once again returns to liquid form. After the expansion valve has caused a reduction in pressure an temperature

Responsibility for Energy and Environment Hovalwerk AG / Nov-14Heat Pumps13 Refrigerant Working media (e.g. refrigerants) are substances that vaporise at low temperatures. If they are then compressed, their temperature rises! The working medium continually changes its physical condition throughout the circulatory process. It vaporises, is compressed, liquefied and then expands again. Treibhauspotential (GWP) Global Warming Potential Greenhouse Warming Potential
