When the Summer Season peaks and temperature increases, people usually find the comfort of air conditioning. There are various types of air conditioners within the Portable and Fixed sectors.
What actually happens inside an Air Conditioning Unit..
Warm air from the environment is removed and cycled to pump out cycled cool air. The compressor cools FREON gas, causing it to become hot pressured gas. This runs through the coils of the unit to dissapate its heat which then condenses into a liquid. The FREON liquid runs through an expansion valve and in the process, it evaporates to become cold, low pressure gas. This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air.
Air Conditioners also clean the air through the build in filters. This is why the Fixed and Portable units have to be serviced on a regular period. Air Conditioning units also remove excess water from the air.
The most important part of HVAC maintenance aspect is maintaining unrestricted air flows. Dust, dirt, and debris are an HVAC system’s worst enemies. Whether it’s an indoor or outdoor unit, you must keep all filters clean and heat exchangers and coils free of restrictions.
We recommend that your heating and cooling system be checked and serviced twice a year; ideally a spring and autumn tune-up. Also we recommend that you change your filter regularly, depending on the type of filter you have. This alone can eliminate many of the most common problems that need fixing and can significantly reduce the likelihood of a serious breakdown.
A portable air conditioner is quite simply a cooling unit to reduce the air temperature. There are various types such as Air To Air, Split Air Con, Industrial Spot Cooling and Evaporative Cooling. The type of unit depends on the application.
It all depends on factors such as ceiling height, room size, number of windows and doors in the room, number of people in the room, access points to the room and types of equipment in the room (computers, machinery etc). On average, you need to provide around 130W of cooling for each m2 of the area with a standard 8ft ceiling height.
