Difference between summer and winter air cooling system
Answers
Answer:
Air Conditioning System
Winter Air Conditioning System
In winter air conditioning, the air is heated which is generally followed by
humidification. The schematic arrangement of the system is shown in Fig.
The outside air flows through a damper and mixes up with the re-circulated air
(which is obtained from the conditioned space). The mixed air passes through a filter to
remove dirt, dust and other impurities. The air now passes through a preheat coil in
order to prevent the possible freezing of water and to control the evaporation of water in
the humidifier. After that, the air is made to pass through a reheat coil to bring the air to
the designed dry bulb temperature. Now, the conditioned air is supplied to the
conditioned space by a fan. From the conditioned space, a part of the used air is
exhausted to the atmosphere by the exhaust fans or ventilators. The remaining part of
the used air (Known as re-circulated air) is again conditioned as shown in Fig.
The outside air is sucked and made to mix with re-circulated air, in order to make
up for the loss of conditioned (or used) air through exhaust fans or ventilation from the
conditioned space.
Summer Air Conditioning System
It is the most important type of air conditioning, in which the air is cooled and
generally dehumidified. The schematic arrangement of a typical summer air conditioning
The outside air flows through the damper and mixes up with re-circulated air
(which is obtained from the conditioned space) The mixed air passes through a filter to
remove dirt dust and other impurities. The air now passes through a cooling coil. The coil
has a temperature much below the required dry bulb temperature of the air in the
conditioned space. The cooled air passes through a perforated membrane and loses its
moisture in the condensed from which is collected in a sump. After that, the air is made
to pass through a heating coil which heats up the air slightly. This is done to bring the air
to the designed dry bulb temperature and relative humidity
