Heat pumps are working on the thermodynamic cycle that moves thermal energy from one location to another with the help of a refrigerant. The basic elements of the heat pump system include: evaporator, compressor, heat exchanger and expansion valve. Let's break down each component:
Evaporator: This component takes heat from the refrigerator’s surroundings: air or the earth to transform the refrigerant from a liquid to a gas. In brands such as LG and Vaillant, this process is very efficient translating to low energy loss.
Compressor: The compressor raises the pressure and temperature of the refrigerant allowing it to carry heat to your home. Wolf heat pumps, for instance, employ high efficiency compressors to increase its capabilities of heating the house.
Heat Exchanger (Condenser): The heat exchanger passes the heat from the refrigerant to the air or water that is used to warm your space. Thanks to, for instance, Viessmann technologies, the heat exchanger enables the highest energy exchange.
Expansion Valve: The expansion valve then drops the pressure of refrigerant and in the process cools which is set to begin the cycle again. This component is very importantly used and has a useful aspect in the performance of the heat pump.
Heat pumps can be classified into several types, each suitable for different applications. Below, we explore the most common types, including their strengths and weaknesses.
Air source heat pumps (ASHP) extract heat from the air and are among the most popular types due to their versatility.
Working Principle: Air source heat pumps operate by absorbing heat from the outdoor air, even in cold conditions, and transferring it inside.
Key Features: These heat pumps are easy to install and can reduce heating costs significantly.
Ground source heat pumps (GSHP), also known as geothermal heat pumps, extract heat from the ground using underground pipes.
Working Principle: These systems use the stable temperature of the earth to heat or cool your home.
Key Features: Ground source heat pumps offer excellent long-term energy savings but can be more expensive to install.
Water source heat pumps transfer heat between your home and a nearby water source such as a lake, river, or well.
Working Principle: By using water as the heat exchange medium, these heat pumps can be highly efficient.
Key Features: These systems are ideal for properties near large water bodies but may require more maintenance.
| Heat Pump Type | Working Principle | Advantages | Disadvantages |
| Air Source Heat Pump | Absorbs heat from outdoor air | Cost-effective, easy to install, low maintenance | Less efficient in extreme cold climates |
| Ground Source Heat Pump | Utilizes stable ground temperature | Highly efficient, long-term savings | Higher upfront cost, complex installation |
| Water Source Heat Pump | Transfers heat to/from water bodies | Very efficient if near water, eco-friendly | Limited to specific locations, maintenance |
When selecting a heat pump, it’s important to understand the type that best suits your property and climate. While air source heat pumps are easier to install, ground source heat pumps offer greater energy savings in the long term. Water source heat pumps provide high efficiency but are best suited to properties near water.
