We installed the air conditioning column only once, and it was in Benidorm at a service station. Do not confuse them with industrial air conditioners, as column models are used in places where high cooling capacity is required and there are no strict requirements for the design of the room. They are similar in size to refrigerators, heavy and installed on the floor. The air conditioning columns require a relatively large area, as they create a powerful flow of cooled air, and it is unpleasant to be near them due to the strong blow.

 Mobile air conditioning, also known as floor-standing, is the only type of air conditioner that can be installed by itself. For its installation, it is sufficient to pull out the flexible hose in a container or open window for hot air. Since the hose is a small length (about one meter), the air conditioner should be located near the window. It is not recommended to lengthen the hose as this may affect the thermal mode of the cooling circuit. The disadvantages of mobile air conditioning systems are high noise from the compressor, limited capacity and a high price comparable to the cost of split-systems. The specialized air conditioning shops in Alicante and other cities have a wide selection of models. Some mobile air conditioners have two air ducts: one that feeds the street air into the device and the other that draws the exhaust air.

  In the past, window air conditioners were widely available in Alicante province, but now, due to reduced demand, they are offered by only a few manufacturers. For the installation of such air conditioner is necessary to cut a rectangular hole in the window glass or thin wall, so that the main part of the device is outside, where through the ventilation grilles heated air. Inside the room there is only a small part of the assembly with decorative panel, through which cooled air enters the room. The power of the window air conditioners varies from 1.5 to 6 kW, the simplest models can only cool down, and more advanced ones are equipped with heating function and remote control.
The main disadvantage of window air conditioners is noise from the compressor.

 The "chiller-fan coil" system is a popular climatic equipment in Alicante province. It differs from other air conditioning systems in that the external and internal units are connected by water or antifreeze instead of freon. Chiller is a refrigeration unit that cools liquid. Instead of air, water passes through the evaporator. This water is then fed through the pump station via heat-insulated pipelines to fan pipes, which are installed in the rooms and serve as internal units of split systems.

The central air conditioner is not an autonomous device, as it requires an external source of cold or heat, such as cold water from a chiller, Freon from an external compressor and condenser unit, hot water from a central heating system or a boiler. In addition to cooling and heating, the central air conditioner can also ventilate, clean and humidify the air. The air treated in this way is distributed to the rooms through a system of air ducts. Modern central air conditioners are manufactured in the form of standard modules, each of which is responsible for its own function: The cooling section consists of a water or freon heat exchanger, using water or antifreeze supplied from a chiller, or freon, which requires an external freon compressor-condenser unit. The heating section is of two types: water heater or electric heater. The water heater is a heat exchanger to which hot water is supplied from the central heating system or a separate heating boiler.
 

 The fan section is used to supply air to the air-conditioned rooms. Central air conditioners use centrifugal fans driven by an electric motor via a belt drive. This section can be placed between other sections or at the outlet of the air conditioner. The sound attenuation section is designed to reduce noise from the fan section and contains sound absorbing plates made of mineral wool or glass fibre of a certain density. The humidification section provides humidification of the air in a nozzle chamber or by means of a steam humidifier, where water is atomised into a finely dispersed suspension that evaporates in the passing air. Behind the humidification section, drift eliminators are usually installed to prevent moisture from entering the ductwork.
 

Roof air conditioner, or Rufftop, is a single-block refrigeration unit intended for installation on the roof of a building. Such air conditioners are usually used to provide climate and ventilation in commercial halls, closed stadiums, conference rooms and similar spaces. The roof air conditioning is similar to a large window block. It includes standard components such as compressor, condenser, evaporator and fans and can be equipped with a mixing chamber to combine recycled and outdoor air, and an electric or water heater for heating in the cold season.
Rooftop air conditioners have a capacity of 8 to 140 kW and a capacity of 1500 to 25000 m3/h. The single-block construction ensures easy installation and maintenance.

Cabinet type air conditioners are usually finished monoblocks and used in production rooms to maintain the required temperature permanently. Their cooling capacity varies from 10 to 80 kW. In addition to the monobloc, there are models with external condenser.

Main features and benefits:

Easy installation and maintenance due to the availability of all components.

Ability to work in a wide temperature range. Unlike split systems, the compressor is installed inside and not exposed to external temperature fluctuations.

The cooled air is distributed either through the top part or directly into the room, or via the air duct system.

Possibility of additional equipment such as electric or water heater, and distribution chamber for even air distribution and noise reduction.

Precision air conditioners, or close control systems, differ from conventional cabinet air conditioners in that they can accurately maintain not only the temperature but also the humidity. These systems are installed in places where strict climate control is required, such as museums, pharmaceutical laboratories, server rooms and production facilities. Humidity control is achieved by integrating a hygrostat and humidifier into the air conditioner. Key features of precision air conditioners include: - Temperature accuracy: ± 1°C - Humidity accuracy: ± 2% - Power range: 5 to 100 kW - High reliability in continuous operation - Ability to operate over a wide ambient temperature range (down to -35°C) - Compatibility with automatic building climate control systems Precision air conditioners typically consist of two units: an outdoor unit containing the condenser and fan, and an indoor unit containing the compressor, evaporator, humidifier and automation system. One of the features is the ability to distribute air through the top or bottom panel, which allows the use of a raised floor for room air distribution.
 

VRV and VRF systems are advanced versions of traditional multi-split systems and are very popular, especially in prestigious building projects on the Costa Blanca, from Alicante to Benidorm. As with multi-split systems, several indoor units can be connected to one outdoor unit, but in VRV systems there can be dozens of indoor units. VRV indoor units can be of different types (wall-mounted, ducted, cassette, etc.) and capacities, usually from 2 to 25 kW. VRV systems differ from previous generations of air conditioners as follows: In traditional multi-split systems, each indoor unit is connected to the outdoor unit by a separate freon line. In VRV systems, all units are connected to a single network of pipes, which allows up to 30 indoor and 3 outdoor units to be connected to two or three copper pipes. This simplifies and reduces installation costs and facilitates future expansion of the system.
 

The maximum distance between the indoor and outdoor units can be up to 100 metres and the height difference up to 50 metres, which gives freedom in choosing the location of the outdoor unit. The indoor units can be controlled either by individual wireless remote controls or by a centralised remote control that monitors the operation of all units and the system status. It is also possible to control through a personal computer. VRV indoor units ensure maintenance of the set temperature with an accuracy of ±0.5 °C, which is higher than that of standard air conditioners. The name VRV (Variable Refrigerant Volume) means "variable refrigerant volume".
