7 Best Heat Pump Consumer Reports 2020 – Top Rated

The heat pump is an efficient system that can be used both for heating and cooling (or air conditioning ) and even for domestic hot water, and can even heat pools efficiently. But as we will see in the different types of heat pumps, not all systems can be used for everything, for example, some will be used only to heat the water and even the reversible heat pump systems serve both to heat and to cool the water. ambient.

How do heat pumps work?

The operation of a heat pump is based on thermodynamics, therefore it transports energy from one place to another. Renewable sources can be 3, air (aerothermal) water (hydrothermal) or soil (geothermal).

But if we collect, for example, the air in winter to have a heating or hot water in the home, the air that we have extracted is cold, so how is it transformed? This is when the operation of the heat pump is presented. Below is an example of how an air-water heat pump works.

Source: industrial technology.

1º External capture. The ambient heat that we have extracted from the outside is transferred into the pipes.

 The fluid antifreeze liquid under pressure ), joins with the ambient heat and extracts the heat in the evaporator. It is mandatory that the antifreeze liquid is much colder than the ambient heat, otherwise, it will not be able to extract all the heat.

 The heat obtained must increase its temperature. To do this, the refrigerant that has the heat evaporates in the evaporator (yes, it gets evaporated although this at low temperature).

 This evaporation called vapor low pressure enters the compressor that works thanks to the electrical energy, in this way we get that it increases much more its temperature.

 High-pressure and high-temperature discharge gases from the compressor enter the condenser and heat is transferred to the external medium due to condensation of the refrigerant fluid.

 The refrigerant has already fulfilled its function of transmitting the heat, therefore it has to return to its cycle again.

 The refrigerant returns to cool, returning to liquid high pressure, but the refrigerant is still too hot, so with the help of the expansion valve we get to cool it again, as it was before. The main function of the vladula is to make an adiabatic expansion, and as a result of it, a cooling of the liquid-vapor occurs. 

And what is the cycle inversion valve? It is the valve that is in charge of inverting the cycle as its own name indicates, this means that it gets the evaporator to function as a condenser and the condenser as an evaporator. This means that the heat pump is reversible. Together with the inverter technology in the heat pump equipment means that its compressor has variable speed, which allows it to modulate its power according to the demand, granting them a high seasonal efficiency.

What benefits does a Heat Pump have?

The heat pumps have many benefits, they are one of the technologies continue to be used in the future for their level of energy efficiency and because it uses renewable energy. Among its greatest virtues it is important to point out that they have a low level of maintenance, add value to the property and it is flexible, being able to use it, for example, in underfloor heating or in air conditioners.

When is a Heat Pump renewable? 
It is one of the big questions and controversies since it is true that heat pumps usually use electricity to function. But it is also true that heat pumps use renewable energy to produce energy: aerothermal, geothermal and hydrothermal.

Heat pumps, types and efficiency 

We can find 4 types of heat pumps and depend on our needs we must choose one or the other.

Air-air heat pump

These heat pumps transfer two elements of the same nature, the air. 

The heat (or cold) that is taken from the air is transported directly to the air in the area that we want to heat (or cool).  Due to their nature, they are generally used to air-condition rooms, since when they only transmit air they can not be used to heat the water.
This type of heat pump is usually the most used, the most economical and inexpensive par excellence, at least generally, although other types of heat pump that are in the same economic band.

Air-water heat pump

This pump uses the heat of the ambient air to heat the water. We can think that this type of pumps can only be used to heat the water of our home or our pool, but the truth is that there are technologies that heat the environment using water, we talk about the radiant floor that promises us on many occasions to save between 15% to 20% more than other technologies.

Water-water heat pump

This type of heat pump is used much less than the air-to-air and air-water heat pump. This is not because it is less efficient, it is more often precisely the opposite, but what happens is that it requires specific conditioning factors that are more difficult to fulfill. The pump exchanges heat (or cold) from an external water source to the water in our home.
