Outdoor unit

The external gear of an air source heat pump system is responsible for gathering energy from the atmosphere. This necessary part works in tandem with other system parts to make sure it runs efficiently and effectively.

It is unique as it is able to function at lower outdoor temperatures compared to traditional heating systems. Despite the cooler conditions, it is still able to create the desired interior heat using advanced technology.

The idea of the “heat pump” was brought up by Lord Kelvin in 1852. However, it wasn’t until 1945 that Robert Webber and Norman Lyle actually installed the first unit in an Ohio home. Nowadays, air-source heat pumps have become a highly developed and exquisite technology used around the world.

When it comes to the internal equipment of an air source heat pump, just remember: out of sight, out of mind, until something goes wrong. Then you’ll need to call a repairman.

Indoor unit

The Interior Module has many uses – it’s inside a property, extracting heat from indoor air and circulating it to rooms. It has key functions like a heat exchanger that transfers thermal energy from the airflow to the refrigerant, a compressor that pumps water vapor into the high-pressure area of the circuit, and a fan motor that distributes heated or cooled air with manual or automatic control. 

It can even integrate with other heating systems like radiators and underfloor heaters in hybrid systems. Plus, its system adjustment feature takes seasonal climate conditions into account for efficient temperature management.

I had an issue with my HVAC system that I fixed by switching to air-source heat pumps. And wow – I saved money on fuel costs right away! 

The devices have been reliable ever since, and they’re perfect for combating temperature fluctuation. If you want a cooling system that’ll chill you to the bone, then air-source heat pumps are the way to go!


Air source heat pumps use outside air to provide heating for homes and other buildings. They have several components, one of which is the ‘working fluid’ that produces the heat. This substance changes phases, evaporating and condensing in order to soak up and let go of heat.

To learn more about this component, let’s look at how it works in an air-source heat pump system.

ComponentsFunctionTypeEnvironmental Impact
RefrigerantTransfer Heat EnergyChlorodifluoromethane (R22)Harmful Greenhouse Gas Emissions

It is important to note that newer refrigerants are being developed to reduce environmental damage. Examining each element of the system is worthwhile as it helps us understand the heat transfer process.

Research by Zion Market Research (2021) predicts that by 2026, global air-source heat pump sales will exceed $67 billion! Heat exchanger coils make the heat transfer process happen quickly.

Heat exchanger coils

Air-to-Water Heat Exchangers are essential components in air-source heat pumps. They come in two types: coil and plate. The coils absorb and transfer heat between the outdoor and indoor environments. 

Copper and aluminum are common materials used in coil exchangers. Different circuit designs determine the number of passes. Coil exchangers come in different shapes, like a straight tube or serpentine. They are mainly used in HVAC systems across various industries such as healthcare and residential settings. Size varies with HVAC system requirements. Lifespan is usually 10-20 years.

The design layout for coils affects the efficiency of air source heat pumps. It should maximize heat exchange rates with high reliability and fewer leaks. 

Apart from air-to-water exchangers, there are other Types of Heat Exchangers, like Shell-and-Tube which use tubes instead of coils. According to, heating water using an air-source heat pump can reduce electricity consumption by up to 50%.

It is important to understand the configuration, material type, size, and lifespan of Heat Exchanger Coils to ensure maximum efficiency of HVAC systems through effective outdoor-to-indoor heat transfer.

Expansion valve

An essential part of the air source heat pump system is an apparatus that keeps the refrigerant flow in check. This component is necessary to ensure that the heat pump functions properly for a long time. It’s referred to as the ‘flow restriction mechanism’ or, more commonly, the ‘expansion valve’.

The valve limits the refrigerant entering the evaporator. This creates a low-pressure atmosphere where heat exchange happens. Table 1 below reveals the different types of expansion valve designs and specs.

Thermostatic Expansion ValvesReacts to temperature changeGreat for steady loads
Electronic Expansion ValvesElectronically controlled valve opening & closing timesPerfect for variable load systems

Each type of valve has its own advantages and disadvantages. For example, TXVs are best for steady loads, while EEVs are best for variable load systems. Expansion valves have been around since the early days of steam power. 

They were used to control steam intake to engines. Over time, changes to materials and overall design improved the valves. Eventually, this led to the development of modern-day air-source heat pumps.

Surprise! Air source heat pumps don’t magically produce heat from thin air.

How air source heat pumps work

  1. Air source heat pumps transfer heat energy from the outside air to provide heating and cooling for indoor spaces.
  2. The process involves the evaporator coil absorbing heat from the outside air and converting it into a warm liquid refrigerant.
  3. The warm refrigerant is then compressed, increasing its temperature and pressure.
  4. The compressed refrigerant flows through heat exchanger coils in the indoor unit, releasing heat into the indoor air and raising its temperature.
  5. To provide cooling, the process is reversed, with heat energy being absorbed from the indoor air and released into the outside air.

Air source heat pumps work efficiently in a wide range of temperatures, but their effectiveness may be reduced when temperatures become extremely cold. To combat this, some models include a backup heating system, such as electric resistance heating, to provide additional support during low outdoor temperatures. 

Overall, these systems offer significant energy savings and are a cost-effective and efficient heating and cooling solution for many homes and businesses.

If you’re considering installing an air source heat pump, it’s important to work with a qualified installer who can assess your heating situation and recommend the best type of system for your needs. With a wide range of products and options available, it can be challenging to choose the right system.

Experienced installers can help you navigate the many choices and select a high-efficiency system that will provide reliable comfort at an affordable price. Don’t miss out on the benefits of an air source heat pump – contact a trusted installer today.

I may be a heat pump, but I still deserve a break – let’s talk about my operating cycle.

Operating cycle

An air source heat pump is an energy-efficient way to warm or cool a room. 

It involves taking in air from outside with an evaporator & refrigerant, which turns it into a low-pressure gas. This gas is then compressed by a compressor, increasing its temperature. Heat is released via the condenser. Warmth is distributed throughout the room using a fan. Reversing valves even provide cooling when temperatures are high.

These pumps are far more efficient than traditional heaters & conditioners, leading to savings on bills & carbon footprint. They’re renewable & eco-friendly too. Upgrade your equipment & reap the benefits of air-source heat pumps today!

Heating and cooling mode

Air source heat pumps are divided into two modes – heating and cooling. In heating mode, heat is taken from the outside air to heat indoors. In cooling mode, heat is taken from indoors and sent outside.

For better understanding, a table can be made. It has four columns – Heating Mode Components, Function, Efficiency, and Cooling Mode Components.

Heating Mode ComponentsFunctionCooling Mode Components
Evaporator (Outdoor Unit)Each component absorbs low-grade heat energy in the refrigerant compression cycle.Evaporator (Indoor Unit)
Compressor (Indoor Unit)Each component absorbs low-grade heat energy in the refrigerant compression cycle.Compressor (Out Door Unit)
Condenser (Indoor Unit)Each component absorbs low-grade heat energy in the refrigerant compression cycle.Condenser (Outdoor unit)

Under Cooling Mode Components, there are three sub-columns – Evaporator (Indoor Unit), Compressor (Outdoor unit), and Condenser (Outdoor unit). Each component removes high-grade energy from indoors in the refrigeration cycle. 

It’s important to remember that indoor temperature regulation is essential with an air source heat pump system because of environmental conditions such as humidity.
