Heat Pumps

Heat pumps are named so, because they "pump" heat from a cold source (external environment in winter or cooled room in summer) and with the help of a refrigerant expel it to hot source (heated space in the winter and outdoors in summer). Because it "enforces" a flow of heat from a cooler to a warmer environment, which is contrary to the "natural flow" of heat (which is from the warmer to the cooler), heat pumps require the consumption of a small amount of energy (usually electricity) to preserve its function.

Heat pumps are the best solution for heating and cooling with a single system

The above shows that the heat pump can be used for heating and cooling.Characterized by the coefficient of performance for heating (COP) and cooling (EER), expressing the ratio of benefitial energy to the one that its "consumed". The prices of these factors is greater than one (in almost all applications) and range (usually) from 3 to 4. This happens because the energy we "get" comes 75% from the external environment and 25% of the energy that we "consume". This is what makes the heat pumps one of the top choices for a heating system.

Applications & Advantages About Heat Pump

Applications

Floor system: That system is operating in water temperatures of 35-45°C for heating and 15-20°C for cooling.

Fan Coils: the installation of the fan coils require water temperatures of 45-50°C (or higher) for heating kai 7-10°C for cooling.

Central air conditioning units: same requirements with the fan coils.

Radiators: heat pumps may cooperate for room heating and with radiators (either common or low temperature), taking account in the heating study the performance of the bodies at the lower temperatures of the heating water.

Traditionally, most HVAC equipment was mounted on metal floor supports or cement bases. These methods have significant disadvantages such as short life span, high work costs and inability to significantly reduce noise and vibration.

With the new anti-vibration mounts for supporting the heat pumps and outdoor air conditioning units, which are made of high quality rubber, all these problems are in the past.

Heat Pumps - common questions and answers

1) What is a heat pump?
Heat pumps are machines that exploit the ambient temperatures in order to draw heat from a source (air, water, soil) and transfer it to the recipient as heating or cooling energy. The principle of their operation is the same as the one applied to the refrigerators and to the air conditioners.

2) Where are they used?
They are used for heating and cooling buildings, combined with radiators, floor-heating and Fan Coils. At the same time they can produce hot water for domestic applications.
