Presentation of air-water chillers
Air-to-water types are the most common chillers due to their practicality. They produce hot or cold water, depending on whether you want to use it for cooling or heating.
Split chillers
Divided machines prove to be a favorable choice for the residential segment, which has a max. They are present up to 200 kW. These types have separate outdoor and indoor units (just like a home air conditioner).
Monoblock chillers
There are compact, so-called also monoblock chillers, above a certain level of performance, these are the only features. Complete automation, control, easy installation – these are the advantageous features. These structures are an outstandingly cost- and space-saving alternative, and their installation is easy and quick to implement. They are already available on the market from 7 kW, and above 200 kW we can almost only find this type of chiller.
Frost protection
In the case of monobloc chillers, frost protection is something that must be taken care of: this can be solved by frost protection electric heating or by creating an external water circuit, so that antifreeze is placed in the water circuit instead of water. In this case, it is advisable to use a heat exchanger to separate the circuit inside the building where we no longer have to worry about the risk of frost, so it is not necessary to provide the entire system with antifreeze, only the segment where it is justified.
The advantages of air-to-water chillers can be summarized as follows:
- reasonable price;
- easy installation;
- small footprint (not inside the building but on the roof);
- maximally environmentally friendly solution for both cooling and heating.
