Heat pump

Heat pump is a complete heating and cooling system in which there is a reversible refrigeration cycle in order to the condenser to become the evaporator and vice versa.

Heat pump consists of:                            
•    The compressor
•    The condenser
•    The evaporator         
•    The expansion valve
•    The four-way valve
•    The control system

The classification of the heat pump is based on:
1.    The means where it pumps from and the means it expels:
•    Air-Air
•    Air–Water
•    Water-Air
•    Ground-Air
•    Ground-Water
2.    The position of the various mechanisms :
•    Uniform or autonomous (Compact)
•    Split or bilateral type (Split Units)
3.    The way the reversion is achieved :
•    Fixed refrigerant circuit
•    Variable refrigerant circuit

The categorization of heat pump applications is based on:
1.    Low Temperature Cooling/ Heating up to 55oC
•    Underfloor heating: The underfloor heating water temperature ranges from 35oC to 45oC
•    Fan coil
•    Cooling/ Cooling Ceiling/ Fan coil.  In system cooling / cooling ceiling water temperature ranges from 7oC to 18oC.  Control of the system is achieved by automating the control of dew point.
•    Hot water (ΖΝΧ)
•    Pool Heating
2.    Middle temperatures up to 65oC
•    The temperature ranges up to 65oC
•    Installation on existing boiler system is simple and economical
3.    High temperatures up to 80οC
•    The temperature ranges up to 80οC
•    Installation on existing boiler system is simple and economical
4.    Geothermy
•    Closed system of shallow geothermy.
•    Open geothermy system

Benefits of Heat Pump
•    Energy saving
•    Enviromental Protection
•    Installation - machinery space
•    Maintenance cost
•    Flexible interface applications
•    Reliability - Quality
•    Smart management
