Air Conditioning Comparisons
May 5th, 2012
There are different types of air conditioners which vary according to size and their functionalities. Each of these systems has a specific type of setting for which it’s more suitable for.
Window air conditioner is the most commonly used especially for single rooms. The major components i.e. compressor, condenser and evaporator are all enclosed in a single box. This is then fitted ion a slot either on the wall or on the window sill. They are the best type of air conditioners for rental apartments as no alterations (such as drilling) are done on the walls. However, their major disadvantage is that they do not include any installation kits such as bolts or frames to secure the unit on the window.
Split air conditioners are comprised of two units: the indoor and outdoor units. The indoor unit comprises of the evaporator, cooling fan/coil. This unit needs no slot for it to be fixed on the wall. The outdoor unit (external condenser box) consists of compressor, evaporation valve and condenser. Unlike the widow air conditioner, it can be used to cool more than one room. They are also permanent and can be installed on various areas such as walls, ceiling or at floor level. However they have a major disadvantage in that they make a lot of noise that can be disturbing to the neighbors.
Packaged air conditioner is specially designed in such a way that it can efficiently serve more than two rooms thus convenient for large homes and offices. This type of air conditioner can be arranged in two ways. First all the major components i.e. compressor, condenser, evaporator and expansion valves can be enclosed in one box. Thus the cooled air will be thrown by the high capacity blower such that it flows via the ducts to the different rooms. The second arrangement is whereby the condenser and compressor are enclosed in one housing such the compressed gas passes through the individual units that consist of cooling coil and expansion valve which are located in the different rooms. The main advantage of this type of air conditioner is that it saves energy as a single conditioner can serve an entire home.
The central air conditioners are used for large applications such as hospitals, hotels and large buildings. The system consists of a plant room where all the large components such as compressor, condenser, evaporator and thermostatic expansion valve are kept. The condenser and compressor can be of tube or shell type. The compressor has multiple cylinders and is cooled using water (like the vehicle engine). The cooled air passed to the different rooms through the ducts. Unlike the other types of air conditioners, this system are more sophisticated although at times can be complex. But computerization has enhanced the addition of electronic utilities that improves on the simplicity of the system. The major advantage of this system is that the amount of cool air needed in a room can easily be controlled depending on the heat load inside the room.
