Central air conditioning

Searching information about participants:

Fan coils

Fan coil is an indoor block. It looks very much like an internal block of a split-system and is similar to it in construction. They can be wall-mounted, ceiling-mounted, stand on floor, be fixed above suspended ceiling. The difference is that they use water (or sometimes ethylene glycol solution) as coolant or heating medium from a chiller, local boiler room or from other piece of equipment. You will have the opportunity of meeting leading manufacturers and suppliers of fan coils.

Central air-conditioning plants

Central air-conditioning plants are used for air conditioning of entire buildings. Since central air conditioner is of a modular type its functions can be of immense variety and depend on the set of modules. A part of them treat air independently and a part depends on the rest components of the air conditioning system. The composition of the system is chosen to meet needs of every separate project.

Chillers

Chiller is a cooling machine used for cooling water. It is the main source of cold in a complex climatic system, its heart. It is often (almost always) the most powerful (and the most expensive) component of an air conditioning, ventilation or an air heating system.

Precision air conditioners

Those are air conditioners capable of maintaining temperature and humidity levels with high precision. They are monoblock units with water cooling or a remote condenser. They are recommended for use whenever high-precision control of air parameters is a must: operating theaters, laboratories, museums, special repositories and so on. They are often used in computer rooms, at telephone exchanges and other places full of expensive electronics equipment.

Forced draft plants

A forced draft plant is a powerful unit for fresh air supply from outdoors to indoors through ventilation ducts. It is a modular unit consisting of several sections. The most important sections are those of ventilation, preheating and filtration. There isn't much difference between forced draft plants and central air-conditioning plants because their functions are similar and they often consist of the same modules. The main difference is in the task set.

Condenser-compressor units

They are used for the conditioning of liquid refrigerant supplied to heat exchanger of indoor block or of central air conditioner. They resemble outdoor blocks of split systems by their construction and appearance. The main reasons for their popularity on the market are their relative cheapness (compared to minichillers), wide range of models on the market and relatively simple site assembly and running.
