"Air conditioning" is defined as the conditioning of indoor air in order to maintain its temperature, humidity, cleanli- ness and air movement at levels suited to human health and comfort or the industrial processes conducted. 1.1 Purpose and Fields of Application or Air conditioning is done for comfort or industrial purposes. People feel comfortable in specific temperature and humi- dity ranges and in environments where the air is clean. "Comfort air conditioning" is the conditioning of air to ac- hieve such an environment. People living in environments with proper comfort air conditioning get...

the air is quite important for human health. In recent years, many diseases have been diagnosed that result from conta- minated or low quality indoor air. Thus, one of the conditi- ons expected from air conditioning equipment is to receive the outdoor air by filtration and removing dust, dirt and mic- The air movement velocity varies with the temperature and the conditions of use of the space. In spaces such as mee- ting rooms and offices where high mobility operations are not conducted, the air velocity should be 0.15 m/s for coo- ling and 0.3 m/s for heating. In spaces of higher activity such...

The most commonly used pressurized tanks include: - Liquid tanks used as coolant depositories - High pressure side tank, low pressure side tank used in liquid pump systems - Liquid transfer tanks The compensating element has one of the most important jobs in the cooling system. Here, the coolant is forced to pass through a small section. Thus the coolant should be fre- e of contaminants. The passage of foreign materials is pre- vented by equipping the liquid line with a filter-dryer. In cooling systems, a quantity of oil leaves the sump along with the hot coolant exiting the outlet of the compressor....

Air handling units condition indoor air with their heating, cooling, humidification and de-humidification functions. Furthermore, air handling units supply the fresh air require- ment of the environment with filtered air. 2.1 Air Handling Unit Performance Standards Up until the 1970's air handling units were expected to pro- vide a determined temperature or humidity, yet with today's developing technology the changing concept of comfort has led to a new approach to air handling units. In line with the needs of our age, air handling units are expected to have ot- her features than temperature...

There is a significant temperature difference between the air inside the air handling unit and the ambient temperature. This temperature difference causes thermal conduction. In order to minimise the value of thermal conduction, i.e. the heat loss from the unit surface, 48 mm thick rockwool insu- lation with a density of 52 kg/m2 and heat conduction coef- ficient of 0.036 (W/mK) is used inside the panel. The heat conduction coefficient of the 1 mm thick sheet material For example, we can calculate the heat conduction value by calculating heat conduction by taking the interior unit panel temperature...
