There is a misconception that air conditioning can make you ill. If it is well maintained, air conditioning only contributes to a healthier environment.

Air conditioning controls the levels of humidity. As you might be aware, humid atmosphere is a breeding ground for the dust mites and molds, which cause different types of allergies. Air conditioning maintains humidity to the levels of 40 to 60 % and prevents multiplication of dust mites and molds. This provides relief to people suffering from different allergies

Ventilation is another important factor for good health. Mechanical ventilation is becoming more important because of changing construction technology. Air conditioning ensures supply of fresh air, which in turn prevents sickness and uneasiness.

Taking care of good ventilation is not enough. You also have to make sure that the air which you breathe is also clean. Air conditioning units are equipped with a filter.
There are different types of filters, suitable for different air conditioning systems. The filter catches dust particles, pollen, bacteria and odours. It even filters microbe and smoke. The air is made pure for breathing. However if you neglect cleaning or replacement of air conditioning filter over a long period, you will be inviting bacteria and other pollutants.

Air conditioning provides clean, pure and cool air to take care of your health.

The Liebert Hiross Flexible Space System is an under-floor air conditioning system that makes use of the vacuum in the floor directly for the distribution of air. Using baffles, supply and return channels are created. Conditioned Air Module (CAM) units are located suitably throughout the office space to generate conditioned air. The CAM units deliver conditioned air in the floor vacuum supply plenums and draw spent air back through the return plenums.

Chilled and heating water supplies are delivered by CAMs by means of small diameter pipe work and condensate water is drained away. While fresh air may be delivered to the CAM from outside or through a central ventilation system, extracted air is usually taken away at high level in the space near risers. Individually controlled fan terminals units are let into the floor over supply plenums. If there is insufficient clearance then console terminal units are suitable as they introduce air into the space above in accordance with the dictates of their own on board control system. Return air grilles are positioned in the floor over return plenum to permit the return of spent air to the CAM unit for re-conditioning. Underfloor baffles control the flow of air and the building is generally divided into several zones per floor that are defined by means of fire barriers place in the floor vacuum.

All CAMs and Fan terminals can be connected into the system permitting control of various functions to take place. The system maybe incorporated with a Building Management System subject to compatibility and requirements.

The Chartered Institute of Building Services Engineers is an international governing body that has been formed for the building professionals to promote the art, science and practice of building services engineering. These buildings basically belong to industries such as those of electro-technical, ventilating, heating, refrigeration, air conditioning and plumbing.

In order to become a trained building services engineers, you ought to fulfil the academic requirement of GCSEs (A-C) or Standard Grades (1-3) in the subjects of Maths and Science, which are crucial in (more…)

The UK has a populace of about 60 million people with around 23 million dwelling in rural areas. More than 20 percent of energy is consumed by the population, which is used for home and water heating in the domestic arena. There is an annual increase of 3 percent in the domestic segment as a whole and 1.4 percent of total energy is used for domestic space heating. (more…)

Acid rain gives rise to Hydro-Fluoro-Carbons (HFCs). The degradation of HFCs would include hydrofluoric acid and Tri-Fluoro-Acetate (TFA) leading to a major impact on the seasonal wetlands in the urban locales

The manufacture of HFCs can also release toxic chemicals, such as vinyl chloride, ethylene dichloride, chlorinated organics, and other HFCs as well as HCFCs into the atmosphere. Liquid traces contain heavy chlorinated wastages that can also include significant amounts of dioxins and chromium in catalyst residues.

HFCs have also been found to contain toxic substances affecting refrigerant technicians who handle these refrigerants, who are then exposed to diseases like skin problems and stomach disorders, as well as other side effects like dizziness and headaches. If there is a fire, HFCs emit poisonous, corrosive and toxic elements when they are burnt.

Hydrocarbons when used as Volatile Organic Compounds (VOCs) use hydrocarbon aerosol propellants, which companies have attempted to use as refrigerants in the past. Nevertheless, it has been realised that VOCs are only available in limited quantities due to their hydrocarbons use, even in 10 percent emissive applications like aerosols. According to market analysts, if all refrigerants used in the UK are converted into hydrocarbons, this would be equal to saving around 10,000 tonnes of hydrocarbons.

Economic instruments play a vital role in the reduction of emissions of greenhouse gases, such as Hydro-Fluoro-Carbons (HFCs). There are many countries looking to apply specific energy taxes according to the given quantity of carbon or energy used by way of downstream taxes imposed on end users.

There has been an increasing trend of encouragement towards using more environmentally friendly non-HFC technologies or solutions, such as hydrocarbons, ammonia and carbon dioxide (CO2). Denmark is already on the forefront of adopting this model of using economic instruments and has suggested a new tax regime focusing on the consumption pattern of refrigerants. The tax system revolves around the Global Warming Potential (GWP).

Normally, the refrigerants can be sold for thousands of US dollars per tonne, and thus, the taxes ought to be fixed appropriately on the basis of magnitude, whilst exerting proper control on the buying pattern of end users. Economic instruments assist in the exploitation of technical opportunities for the reduction of HFC emissions, the vital ones being:

•    Use of a zero or low GWP non-fluorinated refrigerants
•    Use of a NIK technology
•    Reduction of emissions during the lifetime of the product

The use of non-HFC technology and solutions result in varying economic implications. They are also highly influenced by various factors, depending upon the country or region. These include:

• Equipment type
• Equipment application
• Technical support availability (more…)

The increasing use of Hydro-Fluoro-Carbons (HFCs) in commercial and industrial building in the UK has almost created havoc with global warming in recent years. It is estimated that around 95 percent of the climate impact of f-gases or fluorinated gases can be allocated to the industrial use of HFCs. HFCs are mainly used for refrigeration and air conditioning systems in the UK.

Even though at present there are fewer f-gases affecting the UK climate, the UK share of f-gases is expected to rise at a rapid pace in the near future. The reason why f-gases are being increasingly accumulated into the atmosphere is because of the increasing use of HFCs in the UK buildings in place of Chloro-Fluoro-Carbons (CFCs). Moreover, it can also be attributed to the use of HFCs in newer applications, such as car air conditioning systems.

By 2050, no doubt the HFCs usage would look similar to the use of private car transport, affecting the climate change at an equivalent rate. This will also surpass any enhancements undertaken by the Kyoto Protocol. In the wake of many threats posed by f-gases, there are certain alternatives that can be considered to be sued in twenty sectors, except for insecticides and pepper sprays in industries.
