How Heat Pumps Work
Rather than generating heat, heat pumps work by extracting it from one body of air and transferring it to another.
It follows the same principle as your fridge, compressing gas and allowing it to expand, extracting heat as it does so.
Heat pumps can successfully extract heat energy and transfer it indoors to keep you warm, even if the air outside is freezing! In the warmer months, the system works in reverse, extracting heat from inside and shifting it outside, keeping you comfortable and cool.
Heat Pump Heating Cycle
In the evaporator (outdoor unit), low-pressure, low-temperature liquid refrigerant absorbs heat from its surroundings and evaporates, converting to a gas state and absorbing energy as it does so (latent heat of evaporation).
It is then passed through the compressor, where the low temperature gas is reduced in volume, resulting in a rise in both temperature and pressure.
As a heated and high-pressure gas, it passes through the condenser (indoor unit) where the gas condenses (latent heat of condensation) with a release of heat into the air surrounding the coil, a fan moves the warmed air away from the coil to distribute it throughout the indoor space.
Still under pressure, the cooled refrigerant, now in liquid state, passes through the metering device, where rapid expansion results in a reduction in pressure.
In the low-pressure, low-temperature state, the refrigerant flows back into the evaporator, and the cycle is repeated.
Beyond Heating – Air Conditioning Cooling Cycle
When the above cycle is applied oppositely, a heat pump can extract the heat from the indoor air and transfer it to the outside air, consequently, cooling your home or office space.
We have a team of four experienced technicians, trained to undertake the scheduled preventative maintenance checks on heat pumps and air conditioning. The specialised preventative maintenance team is separated from the service department to enable continued maintenance when our servicing team is busy.
Heat Pump Maintenance Frequency
Indoor units should be checked at least once a year. For systems that both heat and cool, autumn and spring are good times to ensure that everything is running smoothly. We check air filters, ductwork and the performance of your system.
Any issues, even those that seem to be minor, can create inefficient systems making them less cost-effective. Organising regular preventative maintenance with us will ensure you aren’t paying more to heat and cool your home or office than you need to be.
For commercial air conditioning installations, preventative maintenance is incredibly important.
Maintenance can be scheduled with at the time of system installation or you can contact us to request our friendly team pay you a visit.
Heat Pumps vs HRV
There is often confusion as to how HRV/DVS/Moisture Master systems vary from heat pumps. It’s important to understand the difference, as the answer is not always simple.
Heat Recovery Ventilation Systems (HRV), and those similarly advertised, are not heat recovery systems, but rather ventilation and positive pressure ventilation (PPV) systems, that function by drawing stored air from the ceiling and dispersing it through ducts into various rooms of the home.
Air stored inside a roof space is usually drier and warmer on sunny days, however there is a limited supply. Pushing warm air into your home allows the system to force out damp air, consequently, reducing condensation.
The drier the home, the warmer it is. However, as the available warm air in the roof space is circulated through the house, it is replaced with cooler air from outside, which is then pushed back into your home, hence reducing the temperature once again.
The air stored in any roof space isn’t particularly fresh or healthy, and often contains dust mites and spores. The system therefore works to purify the air and filter any nasties out, before they enter your home (although not to the same extent as many heat pumps available on the market). The PPV or forced-air system must be heated to continue to provide warm air into your home, which may result in a rise in your electricity bill.
Heat pumps replace existing stale, unhealthy air with fresh, filtered air. They are usually room specific, meaning a single heat pump is unable to warm or cool an entire home. The size of the pump will vary based on the volume of air to be heated/cooled. Similarly, they can be installed internally, allowing the air to be circulated most economically.
The movement of air also helps reduce condensation, yet not always to the same level as a PPV system. Heat pumps are beneficial not only due to their convenience, but also the rate at which they can reach a desired temperature, along with their technologically advanced filtration systems.
Ultimately, the two systems have different functions. One is specifically for ventilation to remedy condensation, while the other is primarily focused on environment control through heating, cooling and air filtration.
In domestic applications most new systems are covered by a 5 year parts and labour warranty (check specific warranty at time of purchase). However, this warranty excludes the breakdown of equipment caused by a lack of regular maintenance (i.e., filter cleaning). For a heat pump system that is used regularly we recommend that the filters are cleaned at least every 90 days. In a normal home or office environment this will keep the system operating efficiently. You can carry out this check yourself and you will find instructions regarding the cleaning in the “Owners Manual”.
Filter Cleaning & Sanitising
We also offer a filter cleaning / sanitising service if required. Heat pump & air conditioning systems can sometimes be blamed for spreading colds and the flu. For this reason we include a special sanitising treatment of the filters in the indoor unit This sanitising treatment is sprayed onto the filter (after cleaning) at each maintenance check to ensure that hygienic air is emitted from the system. This treatment is non-toxic, non-irritating and non-allergenic.
This check includes the following:
- Check operation procedure and control settings
- Clean and sanatise filters (replacement filters extra cost if required)
- Check condenser and evaporator coils
- Check condensate drain and flush if required
- Report on any further work that may be required
