What Is Acceptable In Terms Of Indoor Air Quality
Indoor air quality has been the subject of many debates for several years, mostly about the proper definition of indoor air quality and what constitutes ‘acceptable' indoor air quality.
In the UK, classrooms are required to have 2.5 outdoor air changes per hour. In gyms, dining and other spaces the ventilation should be sufficient to limit carbon dioxide to 1,5000ppm, but in the USA ventilation in classrooms is based on the amount of outdoor air per occupant plus the amount of outdoor air per unit of floor area, not air changes per hour.
Countries around the world will have their own ‘take' on what is acceptable, air conditioning is provided through the removal of heat and all air conditioning units work on this basic principle, heat can be removed through radiation, convection, and by heat pump systems through a process called the refrigeration cycle, thus an air conditioner provides cooling, ventilation, and humidity control for all parts of a house or building.
If we do not know anything about a subject we tend to stick our heads under the sand, but air conditioning is now becoming part and parcel of life in the UK, thus some knowledge of how things work has got to be a bonus.
The refrigeration cycle consists of four essential elements to create a cooling effect. The compressor pumps the refrigerant gas up to a high pressure and temperature, from there it enters a heat exchanger which is sometimes called a ‘condensing coil' this is where it loses heat to the outside, in this process the refrigerant condenses into a liquid, the liquid refrigerant is returned indoors to another heat exchanger called ‘evaporator', as the liquid refrigerant evaporates it absorbs energy from the inside air , returns to the compressor and the cycle repeats, the whole process is removing heat from indoors and transferring outdoors resulting in cooling of the building.
The whole system can work in reverse and can switch from cooling in summer to heating in winter, just by reversing the flow of refrigerant; the heat pump refrigeration cycle is changed from cooling to heating or vice versa.
Dehumidification in an air conditioning unit is provided by the evaporator, controls the humidity of a room or building, and is often installed in basements which have a higher relative humidity because of their lower temperature and tendency for damp floors and walls.
There are all types of air conditioning, and the typical system for home owners is a split system, and although mostly seen in residential homes, they are gaining popularity in small commercial buildings.
All modern air conditioning units are equipped with internal air filters, and are sometimes of a light weight gauze-type element and must be replaces as conditions warrant, for example a building in a high dust environment will need to have the filters changed more often than maybe other building or homes.
A spokesman for Climachill air conditioning specialists said "we have the solution to all air conditioning requests; all systems installed by Climachill have ‘heat pump' technology so that you can use the system for energy efficient heating during the winter months, more importantly the customer can be confident with our whole process of installation and after sales support".
Take advice from professionals and make sure you install a system that will give you the acceptable level of indoor air quality.
