Mechanical Air Conditioner

It  is  a  compact  mechanical  system(including fans, evaporator, compressor, condenser and air filter) to control the indoor temperature and humidity.

• Both window-type and split-type conditioner are not effective air ventilation systems, as they are designed to condition indoor air (Fig 3a).
• Must be complemented by exhaust fan with some opened windows or louvers in order to provide adequate fresh air, even if some air conditioners have vent valves within their systems (only a small opening) (Fig 3b);
• Switch on circulating fan to enhance air movement within the premises;
• Remove any obstruction to the ventilation inlet or outlet; and
• Clean the air filter and AC louver regularly;

Mechanical  Central Air Conditioning System / MVAC

It is a system used to off-set generated heat, control humidity, and deliver fresh air into a building or large space area.

• Ensure each room has sufficient fresh air supply from the system;
• Remove any obstruction to the ventilation inlet and outlet;
• Switch on circulating fan to enhance air movement within premises;
• Clean and/or replace air filters and the system regularly; and
• Proper inspection, cleaning, testing and maintenance schedules for the system should be drawn up and followed.
