Heat Pumps: Overview

A heat pump is a mechanical device or machine that enables the transfer of heat energy from one body or location to another by using work. Speaking in pure technical terms, a heat pump is a device which operates in a cycle and maintains a body at a temperature which is higher than that of the surroundings by virtue of temperature difference. The body from which heat is extracted is called the ‘source’ and the one to which it is transferred is called the ‘sink’. Heat pumps are used to warm buildings or cool them according to the need. Heat pumps can produce the cooling effect when operated in the reverse cycle.

The heat pump has a set of four components that make up the whole system. All the four components are connected through a sealed line or piping in which a fluid called the 'refrigerant' flows.

These are:

    Compressor Condenser Evaporator Expansion Valve

The compressor does the work of compressing the fluid thereby increasing its pressure and temperature and delivering it to the condenser. It is the most expensive part of a heat pump since it has moving parts. The compressor in a process consumes work, which has to be externally supplied. The condenser is a heat exchanger device which condenses the hot fluid supplied to it from the compressor i.e. converts the fluid from the vapor form to the liquid form by transferring its heat to another medium such as air or water.

The expansion valve is a device used to lower the pressure of the fluid to be sent to the evaporator. In the process, the temperature of the fluid is also significantly decreased. Its basic operating parts are the nozzle which lowers the pressure and the valve which controls the fluid supply. The evaporator is also a heat exchanger just like the condenser but its task is exactly the opposite. The evaporator is also a coiled component which converts the fluid from the liquid lo temperature state to the gaseous high temperature state. The heat of the medium is used for evaporation of the fluid and in exchange the medium gets cooled.

One important parameter through which the performance of a heat pump can be gauged is the ‘Coefficient of Performance’ or COP. It is the ratio of the heat transferred (desired effect) to the work done (input). Generally COP lies in the range of 1.0 to 5.0. COP is very similar to efficiency of any machine, but it is not used in this case as its thermodynamic definition is quite the reverse. The design of the evaporator and condenser and the temperature differential between fluid and heating or cooling medium affects the COP.

Basically, heat pumps can be categorized into two main types based on the basis of the sources used:

  1. Geothermal
  2. Air Source
The geothermal heat pumps extract heat from the ground or groundwater. Since the ground remains at a constant temperature, such pumps are highly efficient. The geothermal pumps are categorized into ground, rock and water pumps. The ground and rock type pumps have their piping buried under the soil or a rock shelf while the water heat pumps have their piping under water bodies such as pools and lakes. They are more efficient than the other two types. The geothermal heat pumps are relatively more costly installation wise.

The air source heat pumps use air as the medium for transfer of heat. Due to this fact, they are easy to install and cheap. However, they are much less efficient because the temperature differential of the outside air varies according to the weather and the climate even during a single day.

There are other types of heat pumps also apart from those mentioned above. The Gas fired heat pumps also called Absorption heat pumps use the heat energy of the fuels as the primary source for running the device instead of an electric motor. The fuels used can be LPG or natural gas.

The Central distribution heat pumps use a central distribution network to direct heated or cooled air to different portions of the space. The network consists of ducting, which connects the various sections of a house or a building to the central pump.

The ductless mini-split heat pumps do not use the duct s to transfer the heat. Instead, in such a system the refrigerant that is cooled in the outside unit is then taken through thin pipes to the sections of the building where fans blow the air to affect the air circulation.

A split system heat pumps, which is very common has one of its coils located outdoors and the other one indoors. Both the units are connected to a fan unit that is installed indoors for air circulation.

Dual fuel heat pumps combine the benefits of both electricity and fuel to make a more efficient system. Such a system automatically switches to one of the sources according to the temperature difference of the air outside and the refrigerant. It has a control and sensing mechanism which handles the switching function. It lowers the heating costs by better utilizing both the types of sources.

Heat pumps are most commonly used for Heating Ventilation and Air Conditioning (HVAC) purposes in residential areas. They are also used in industries to provide heat for a particular process. In The food processing industries and refrigeration and storage plants, they are used for processing and preserving food.
