Air conditioning is a familiar and, in fact, mandatory characteristic of any new or renovated modern premises, whether it is a residential building, office or industrial facility. Air conditioning is a necessary condition for a comfortable human sensation, which, as practice shows, helps to increase efficiency and activity, which is very important for the effective economic activity of a modern enterprise.
Industrial air conditioning is a special area in air conditioning, because it uses powerful and complex air conditioning systems, systems with chillers and fan coil units, cabinet air conditioners, compressor and condenser units, etc. All of them allow you to create a comfortable microclimate and a healthy atmosphere in almost any room.
All industrial air conditioning systems can be divided into two groups - with water cooling (chillers and fan coil units) and freon systems.
Such air conditioners are designed for servicing rooms that occupy a large area and volume, and can be used not only in workshops and large industrial premises, but also in indoor sports facilities, concert halls, etc. They structurally consist of separate typical sections hermetically connected between a duct system. Each section is mounted on a frame of aluminum profiles, and is closed with panels, some of which are removable for access to air conditioning units. In addition, each panel is two-layer, with a mineral wool heat-insulating gasket between the layers. A combination of central air conditioners with air heating systems of the building is also possible, then the system as a whole works year-round. Central air conditioning systems with air recirculation are also carried out: in this case they are equipped with a mixing chamber, which allows to supply variable volumes of both fresh, outdoor air and recirculated air.
Such devices can provide independent temperature control in a large number of rooms at the same time, therefore they will be convenient in large office buildings, divided into separate rooms, as well as hotels, shopping malls, etc. The chiller is a refrigeration machine designed to cool the liquid, as which is usually water or a non-freezing liquid. This liquid then enters the fan coil with the help of a pump station - a device in which there is a heat exchanger with a fan, a filter and a control panel. When installed in a room, the fan coil with the help of a fan “collects” air in the room, which is then either cooled or heated on the heat exchanger. A certain amount of fresh air can also be supplied to the fan coil from a central air conditioner or air supply unit, then the system also allows you to solve the ventilation problems of the room. A characteristic feature of chiller-fan coil systems is the flexibility of planning and control, if necessary, air conditioning in a large number of rooms. You can also commission the facility gradually by connecting fan coil units to the system as parts of the building are constructed.
Air-cooled compressor and condenser units are installed outdoors, and a cold consumer (evaporator) is installed indoors. They can be with axial fans, the main advantage of which is lower cost, and with centrifugal fans. In the second case, the noise level in the room is significantly reduced due to the installation of silencers in the ducts, but additional installation work is required to lay the pipelines. There are also condensing units for water cooling. In this case, a monoblock with a compressor and a condenser is located in the room, the condenser is cooled either by a closed circuit with non-freezing liquid using a heat exchanger with fans outdoors, or by running water (artesian or sea, river). The main advantages of such blocks are the possibility of year-round operation, almost unlimited distance between the indoor unit and the outdoor.
This is a monoblock chiller, which is installed on flat roofs of buildings, or on special frames for installation on sloping roofs and on the ground. Such air conditioners can simultaneously ventilate and condition the air in the room, and are suitable for any large-volume premises. In this case, fresh air is taken from the street through the intake grille of the air conditioner, recirculated air enters the room through the duct system, and is mixed with fresh air in the mixing chamber. The use of roof air conditioners allows you to completely save the interiors of the premises, since only air grills are visible inside. Thanks to the monoblock design, these air conditioners are easy to install and they are similar to central air conditioners.
