Air Conditioning

Comfort air conditioning is specially designed to create a 40%-60% humidity rating in the given space. In food retailers large open chiller cabinets are used as highly effective air dehumidifying units.

A specific type of air conditioner that is only used to take humidity out of the air, this is called a dehumidifier. Dehumidifiers are different from regular air conditioning units, whereas both the condenser and evaporator coils are placed in the same air path, the entire units are placed in the air that wants to be conditioned (in this case dehumidified), rather than the condenser coil being outside. Having both the condenser coil and the evaporator coil in the same air path produces warm, dehumidified air. The evaporator coil is placed in the first air path, dehumidifying the air just like a regular air conditioner does.

Cleanrooms also use them for the production of integrated circuits, pharmaceuticals etc, in which very high levels of air cleanliness and humidity control is needed to successfully complete the process. There are many other areas that use process air conditioning, for example, Breeding laboratories, aircraft air conditioning, data processing centres, Textile factories, physical testing facilities, plant nurseries, nuclear facilities, laboratories, mines and food processing areas.

In all of the above mentioned circumstances the air around will not only need to be temperature controlled but also to control the humidity, the air quality, air motion and air movement.

Humidity Control

Air conditioning equipment reduces the humidity of the air controlled by the given system. The relatively cold evaporator coil condenses the water vapour from the processed air sending the water to a drain and removing water vapour from the cooled space thus lowering the humidity in the given room. Since humans perspire, to provide natural bodily cooling by the evaporation of perspiration from the skin, dry air provides a more comfortable surrounding.

Comfort air conditioning makes the process of deep plan Buildings feasible (a deep plan building is where the horizontal distance from an external wall is far greater than the floor to floor height, deep plan building is a method that makes more efficient use of the given area.). A building without air conditioning must be built narrower or with light wells so the inner space will receive sufficient outdoor air, otherwise known as natural ventilation. With the use of air conditioning, buildings can be taller as wind speeds increase significantly, making natural ventilation unsafe and impractical for very tall buildings. Comfort applications for various buildings are different and may be categorized as one of the following:

1)      A Low-Rise Residential building, including family houses, duplexes and small apartment buildings.

2)      A High-Rise Residential building, such as dormitories and apartment blocks.

3)      A Commercial building, built for commerce, such as offices, malls, shopping centres and restaurants etc.

4)      An Institutional building, such as hospitals, governmental buildings, academic buildings etc.

5)      Industrial buildings/ spaces where the thermal comfort of workers is desired.

Air conditioning is not only used in buildings, it is also used widely in a variety of transportation such as Vehicles, Ships, Trains, Aircraft and Spacecraft.

Air Conditioning engineers tend to separate air conditioning into 2 applications, either comfort or process.

Comfort applications are aimed to give buildings a building indoor environment that is controllable and can be kept to a consistent temperature within the idyllic temperature for humans to work. The system given here would need to keep the indoor at a constant temperature regardless of the temperature outside.

The preferred temperature for people in a seated office environment is 22ºC, at this temperature, (which can be achieved by air conditioning) it has been proven that optimum workloads are reached, performance has been proven to decrease by 1% for every 1.5ºC change in the room temperature. The optimum temperature in a standing position tends to be at a slightly lower temperature. For shorter people the highest performance level tends to be at a slightly higher temperature.

The Hawthorne effect is described to enhance work productivity with the use of air conditioning (creating a thermal comfort).

Just Coolers is the U.K.  No. 1 air conditioning company offering honesty, reliability and a first class service. We always carry huge stock inventory with fully stocked spares department and can offer you the highest level of air-con quality products at extremely competitive prices.

Choosing an Air Conditioning company is a daunting experience by any means. At Just Coolers, one call does it all.

  Just Coolers Air Conditioning is safer and more efficient than many other forms of heating.

With air conditioning heating it’s simply the refrigeration process being reversed, so that the warm air comes out inside the conservatory and the cold air goes outside.
