» What is an inverter heat pump?

Inverter technology has revolutionised the air conditioning industry and the inverter heat pump is one example of this. This air conditioning system uses a renewable energy source such as outside air to provide heating or cooling in a given space. Inverter technology is a major breakthrough as it makes it possible to achieve greater climatic comfort more quickly and with significantly lower energy savings. In this blog post, we will take a closer look at how the Inverter heat pump works, its advantages and disadvantages, and the applications in which it is used.

What does the term “inverter” mean?

The term “Inverter” refers to a more efficient type of technology used in modern air conditioners and in this article we will mainly refer to domestic air conditioners although this technology also works in commercial and industrial air conditioners.

In the past, the old air conditioners worked in a way known as On-Off, that is to say, these units always worked at maximum power to reach the desired temperature and once this temperature was reached, they were switched off, so that the compressor was constantly on and off, which made them very inefficient.

To solve this efficiency problem, air conditioners with a technology known as “inverter” were developed. Instead of turning the compressor on and off at full power to reach the desired temperature with an inverter system, the compressor spins continuously, adjusting its speed to maintain a constant temperature in the room. This means there are no temperature rises and falls, and no energy is wasted in turning the compressor on and off all the time, making energy consumption much more efficient. Also, as the compressor does not have to work as hard, its lifetime is longer.

Currently, On-Off air conditioners are no longer at sale.

How an inverter air conditioner works

First of all, an inverter system detects the ambient temperature of the room and compares it with the desired temperature.

The greater the difference between the two temperatures, the greater the capacity we will need from the compressor, so we will make it rotate at a higher speed. For this same reason, when the desired temperature is reached and as long as the difference between the room temperature and the desired temperature does not exceed 2º C, the equipment will start to work constantly and at low power to maintain the desired temperature.

If the air conditioning unit is correctly sized, the compressor will never switch off while it is running, which will allow it to maintain a stable and constant temperature in the room, providing greater comfort and lower energy consumption.

For this reason, it is essential to have the advice of a professional air conditioning installation expert to choose the right size and model. This will ensure a correct and optimal installation of the equipment, resulting in energy savings and better performance of the equipment.

Advantages of Inverter technology

• Lower noise levels: Air conditioners with Inverter technology are quieter, as the compressor and fan run at lower speeds and there are no constant on/off starts.
• Greater comfort: These units also offer greater comfort, as they maintain a stable room temperature without sudden changes.
• Greater savings on energy bills: Inverter technology allows great energy savings, as it regulates the compressor’s operating frequency, which can save up to 40% energy compared to an ON/OFF air conditioning unit.
• Longer life: By avoiding constant start-ups and shutdowns, the workload of the appliance to achieve the desired temperature is reduced, which can lead to a longer service life.
• More efficient heat pumps: While heat pump air conditioners without Inverter technology stop working properly when the outside temperature is 0ºC, Inverter heat pump air conditioners can work properly even at extreme temperatures as low as -15º.

Uses of the inverter heat pump

Inverter technology is widely used in a variety of air conditioners for domestic, commercial and industrial use. For domestic equipment, Inverter technology is commonly found in air conditioning systems such as split, multi-split, aerothermal or ducted systems. On the other hand, in the case of commercial or industrial equipment, Inverter technology is used in Variable Refrigerant Volume Refrigerant (VRF) installations, which allows for greater efficiency and control in the air conditioning of large spaces.

Comparison

InverterOn-Off Lower energy consumption up to 40% less than an On-Off system.Higher energy consumption Greater comfort due to the fact that once the desired temperature has been reached, they continue working at lower power to maintain the temperature.Less comfort as the temperature rises and falls constantly. The device starts up smoothly and progressively, which makes consumption more efficient.The device starts up abruptly, which leads to high electricity consumption. The compressor speed is efficiently regulated to match the desired temperature and constantly rotates to maintain the desired temperature.The compressor always works at maximum power to reach the desired temperature and once it has reached it, it switches off and switches back on again at maximum power in order to maintain the desired temperature.
