Q: How does an air conditioner work?


A: Air conditioning systems work by moving heat from inside your premises to the outside with the use of refrigerant gases. It works on basically the same principle as your household fridge.

Q: Is the equipment noisy when in operation?


A: No, one of the most important design criteria for the equipment manufacturers is a low operating noise level. Many air conditioning systems incorporate ‘quiet’ or ’silent’ modes, which provide sound levels as low as 22 dB(A) from the indoor unit and 43 dB(A) from the outdoor unit. In basic terms, you have to be within 2 or 3 metres of these units in a quite environment to hear any indication that the air conditioning is working, though in larger applications, outdoor unit noise levels are increased. Noise reducing techniques/equipment can be implemented if required. 


Q: Please explain the difference between air conditioning, comfort cooling and close control?


A: Air conditioning covers many things but is mainly, heating, cooling, ventilation, fresh air, filtration and control of humidity.

Comfort cooling mainly relates to provision of just cooling to improve comfort.

Close control air conditioning is really as the name implies, both temperature, humidity and air cleanliness are closely controlled and often to fine tolerances if necessary.
