What aerothermal heat pump capacity do I need?

In this article, we will try to answer the question: what aerothermal heat pump capacity do I need? So that, when the time comes to decide, you have a clearer idea.

But before we address this question, we will look at what an aerothermal heat pump is, what it is used for, and how it works.

What is an aerothermal heat pump?

An aerothermal heat pump is equipment used to heat or cool water. They are very common in homes and buildings. The first aerothermal heat pump was invented by Willis Carrier in 1902, and its main component is the compressor.

They can be of many types and sizes, depending on the user’s needs. One of the advantages of operating an aerothermal heat pump is that the system is environmentally friendly, as it does not emit gases and does not pollute the air.

Most elements of this equipment use the evaporative cooling system to move water up and down. Evaporation is a natural process that occurs when a hot body cools down and loses part of its heat through contact with a cold body.

Aerothermal heat pumps are used in many types of industry, from agriculture to the chemical and food-processing industries.

Renewable energy plants can also include these devices as part of their electricity generation system, as can domestic systems in small and medium-sized homes.

Each type of machine requires a different configuration depending on the equipment needed to control it and the airflow required for its operation.

For air-conditioning equipment to work, a refrigeration system is required. Without refrigeration, heat cannot be removed from the environment. The refrigeration machine works like a pump that goes from the compressor to the evaporator and then returns to the compressor.

In the final stage of the cycle, the superheated wet vapour is cold-condensed to become a clear liquid (water). The clear liquid recirculates through the evaporator to keep it cooled.

How much power does an aerothermal heat pump have?

The power of an aerothermal heat pump is the amount of heat it can produce. Depending on the type of machine, it is possible to find differences of 10% to 20% between models.

Power is determined based on the unit’s average thermal performance and is related to its rated thermal capacity (in W). A machine with a rated power of 1 kW produces 1 kW per hour, which is equivalent to 3,600 W per minute (3,600 W/h).

When it comes to the power of an aerothermal heat pump, it is important to ensure that the correct type is used for a specific installation. Power depends on the type of start-up and the cooling the building requires.

Most manufacturers can provide a power estimate in their specific designs regardless of the customer’s geographical location and environmental conditions.

Power can also vary depending on the number of windows and doors on each floor of the building. For example, if a building has a total of 100 windows and doors on each floor, then two aerothermal heat pumps will be needed to cover the entire space.

The size of the machine is established based on the volume and temperature of the air to be heated. The manufacturer usually recommends a power rating for each of these factors, but this is not always the case.

The power of an aerothermal heat pump is related to its ability to raise the air temperature.

Next, we will determine what heat pump capacity I need based on the characteristics of the building where it will be installed and the benefits we want to obtain.

What aerothermal heat pump capacity do I need?

The capacity of an aerothermal heat pump depends on several factors. For example, whether automation is a priority, the type of industry, and whether there are heat losses in your installation. But how do you know what aerothermal heat pump capacity you need for your project?

To begin with, we need to define what efficient capacity is. An energy-saving machine is one that uses as little energy as possible to produce the same results as others.

This means they perform better in low-vapour environments and low internal pressure, under normal conditions. Therefore, if there is a lot of vapour or high internal pressure (for example, in thermodynamic plants), they are not as effective.

To calculate the power required for an aerothermal heat pump, it is necessary to bear in mind that hot air is used as a resource that is stored and not as a resource that is consumed. For this reason, the machine’s capacity must be large enough to meet customer demand, regardless of whether there are peaks or not.

A question many people ask is: what aerothermal heat pump capacity do I need to heat my home? The answer depends on the number of rooms, their size, and the level of comfort you want to achieve.

The power of a natural gas appliance is measured in kW and depends on the radiator’s capacity and the ambient temperature.

For example, if we have a 100-litre radiator and want its temperature to rise to 55°C, we would need a machine with more than 8 kW of capacity. In this case, the heat produced by the radiator would be well below what is required to maintain the environment under these conditions.

The capacity of the aerothermal heat pump must be calculated depending on the type of installation you want to carry out. For a domestic sanitary installation, for example, machines between 2 and 4 kW are usually used (maximum 5 kW). In the case of an industrial or commercial installation, machines between 5 and 10 kW are usually used (maximum 20 kW).

Power is an important piece of data to consider because it directly affects the energy consumption you will have to pay at the end of the month.
