Installation and Operation of Retrofit Air Source Heat Pump
To install and operate a retrofit air source heat pump system with optimal performance, you need to consider various aspects of the installation process. Two key sub-sections you should pay attention to are ASHP devices and air handlers, and heating system design and distribution system lines. In this section, we will discuss these sub-sections in detail to help you make informed decisions when it comes to retrofitting your heating system with a heat pump.
ASHP Devices and Air Handlers
Devices and Handlers for Air Source Heat Pumps
To make a retrofit air source heat pump work well, you need to understand the devices and handlers. First, the air source unit or outdoor unit. It takes heat from the outside air and turns it into useful heat inside the building. Then comes the indoor unit, the air handler, or the evaporator coil. It distributes warm air into different rooms.
To explain this better, we made a table. It shows the ASHP devices and what they do:
| Device | Function |
| Air Source Unit | Extracts outdoor air energy |
| Compressor | Increases pressure of refrigerant |
| Condenser Coil | Releases heat energy into inside space |
| Expansion Valve | Lowers pressure of refrigerant |
| Evaporator Coil | Absorbs heat from the air inside building |
It’s important to know each piece plays a big role in making the system efficient and saving energy.
When you select an air handler for your ASHP system, think about its capacity and duct size. If it’s not right, it can cause problems and cost more to run. Also, maintain filters, coils, and condensate pans often. This helps keep the system working right.
By understanding the components and taking care when you choose them, you can get long-term savings and help the environment by reducing your carbon footprint.
Heating System Design and Distribution System Lines
Designing the heating & distribution networks for a retrofit air source heat pump is key for optimal functioning. Analyze these beforehand to save time & money.
When sizing the distribution system, factor in adequate insulation. Plus, all components must be compatible with the refrigerants used.
Proper installation of heating systems can increase energy efficiency by up to 50%. So, design the networks appropriately to reduce carbon footprint.

When planning an air source heat pump retrofit, it’s important to consider specs and prerequisites for the equipment needed. Factors such as building design, geographical location, weather, and energy needs affect the selection process.
Understand the necessary units and apparatus to ensure success. This includes an outdoor unit in a sheltered area, an indoor unit that can be installed in the same space as existing heating or cooling systems, a refrigerant that must comply with regulations, and a compressor that should be sized for both heating and cooling needs.
Check that the equipment chosen has a good Coefficient of Performance (COP) at low temps, and take into account noise levels for outdoor units. Consider incorporating acoustic enclosures to meet local noise pollution laws.
It’s worth noting that these requirements may differ depending on individual system requirements. GreenMatch states that these heat pumps are becoming popular due to their eco-friendliness, but beware, they may leave you shivering in the cold!
Indoor Noise and Heating Loss Issues
Air source heat pumps for retrofits can cause significant noise and hearing loss issues. Heat transfer from the outdoor unit to the indoor space can generate noise that disrupts occupant comfort. Plus, inadequate installation, sizing, or insulation can lead to high energy bills and heat loss.
It is essential to select an appropriate heat pump size. Be sure it’s neither too small nor too large. Also, sound barriers or enclosures can be installed around the unit for noise reduction. Insulating and sealing ductwork and walls helps reduce energy losses.
