Heat Pumps

A heat pump is a device that uses mechanical work to transfer heat from a colder source to another, warmer body. Popular examples of heat pumps are refrigerators and air conditioners. According to the type of heat exchangers, the heat pumps are air-to-air, air-to-water, water-ground to water and ground to water. The most commonly used heat pumps are air-to-air. Heat pumps can work bi-directionally (transferring heat from the first heat exchanger to the second or vice versa), thereby heating or cooling the environment that needs to be conditioned.

The efficiency of the heat pumps is determined by the ratio of the electricity input to the transferred heat to the conditioned environment. Typically, this ratio is greater than 1, which is explained by the fact that heat is not “produced” but only transferred (pumped) from one medium to another. The “pumping” of heat energy is the easier when is smaller the temperature difference in the two media (respectively in the two heat exchangers bordering the environments). In other words, the efficiency is directly dependent on the temperature difference.

Many industrial processes associated with cooling or heating can be made energy efficient by using heat pumps. For the specific case, we will offer the most effective solution. Please contact us to offer you an energy efficient solution with a heat pump in combination with a renewable energy source.
