Air conditioning

Depending on where the additional free energy is taken from, heat pumps are divided into air–water, water–water and ground–water pumps.

Besides great comfort and efficient heating, a heat pump also allows very economical cooling in summer. Put simply, unlike any other heating device, where you pay for much more energy than you use, with a heat pump it is the other way round: you get several times more energy than you pay for.

Multi-split is a system in which several indoor units can be connected to one outdoor unit, so that several rooms can be cooled or heated at the same time — in a multi-storey house, an office or an apartment complex.

Servers, especially when stacked in rows, produce a large amount of heat that has to be removed by continuous cooling and humidity control. This is a particular challenge, but it can be solved with specialised units designed for server rooms. Each server room is equipped with two indoor units connected to one outdoor unit. If one fails, the other automatically takes over. At any moment one of the two indoor units is running while the other is ready for servicing.

Because uninterrupted cooling of server rooms is so important, the system is managed by a controller that monitors and controls up to 16 indoor units — either directly or through the building-wide control system. The system includes a “duty sharing control” device that locks the server centre’s parameters so that staff cannot change them.

To achieve the optimal microclimate in a pool hall, besides water and air temperature it is very important to keep the relative humidity of the air within limits of up to 60%. This matters not only for a pleasant microclimate but also because it is the most effective way to protect the building structure and installations of the pool hall from increased moisture. For that reason, dehumidifiers and air conditioning are essential in indoor pools.

The most suitable type of dehumidifier is selected according to the area of the pool and the area and layout of the glazed surfaces of the pool hall. Whatever the pool, these are as a rule the most expensive units related to the pool, its technology and equipment. It is very important to plan the necessary openings for the dehumidifier or air-conditioning installations while the building is under construction, and to provide adequate space for the units themselves.
