If the installation is done accurately your air conditioner will give optimum cooling, but if it is not done properly you won’t get the desired cooling effect.

A poor installations also leads to frequent maintenance problems. Several factors have to considered during the installation of split air conditioner. Strength of wall to hold the AC The indoor unit of split AC must be installed on a wall strong enough to hold the unit’s weight. Proper spacing between wall ans AC unit The indoor unit of split AC requires at least 15 cm of open space surrounding its top and sides for proper air flow. Appropriate installation height from ground The indoor unit of split AC should be mounted at a height of 7-8 feet above the ground for adequate cooling inside the room Correct tilt angle of indoor unit While fixing the aluminum bracket on wall make sure that the bracket is given a slight tilt angle, so that the indoor unit of split AC, when fitted is also at a slight angle to enable unrestricted flow of the condensed water from the drain pipe. Correct location of outdoor unit For proper cooling the indoor and outdoor units of split AC should be mounted at location away from direct sunlight and water.

The outdoor unit of split AC should be installed in open space so that there is no hindrance to the heat dissipated from the condenser. Proper placement of outdoor unit The outdoor unit of split AC must be placed on a flat and rigid surface. This unit contains key components of split AC like compressor, condenser, fan motor etc. If the unit is not placed on a flat surface then it will vibrate excessively, which can lead to the breakage of copper pipes, coolant leakage and compressor/condenser damage. Further, the vibrating unit makes lots of noise which could disturb you and your neighbors. Right distance between indoor and outdoor unit Correct distance between the indoor and outdoor unit plays a very important role in cooling. The coolant at very low temperature flows inside the copper tubes between indoor and outdoor units of split AC. There is always some loss of cooling effect to the atmosphere when the refrigerant flows between the units. Hence to reduce this loss, the distance between the indoor unit of split AC and the outdoor unit of split AC should be kept as minimum as possible.

The maximum allowable distance between the indoor and the outdoor units of split AC can be about 15 meters.Heating Ventilation and Air Conditioning (HVAC) is the technology for indoor and automotive ambient comfort. HVAC facilitates in managing the pleasant climate inside the cabin by controlling the degree of hotness/coolness. There were times when having an air conditioner in a car was considered one of the big features, but today air conditioners have become standard equipment even in entry-level automobiles. The desire for even more comfort and luxury has led to the development of the climate control system inside an automobile. The primary purpose of automatic climate control is to manage the temperature of a given area for the comfort of onboard passengers. HVAC was first introduced into automobiles in the early 1960s, and is available in most of the high-end vehicles today. It is a complex system consisting of mechanical/electronic switches or knobs in the frontend. The backend of the system comprises one or more blower motors, actuators (for fresh air circulation control, air-flow control and temperature control), and refrigeration unit coupled with many ducts through which air is transferred to the cabin.

The basic principle behind the operation of HVAC unit is conduction and convection. Heat is transferred from a low-temperature region to a high-temperature region in the vehicle, due to the pressure difference. This process of heat transfer is called Refrigeration. Figure 1 shows the cycle diagram of the complete refrigeration process. An air conditioning system comprises five major components: The five major components are divided into two pressure regions: the high-pressure side is the condenser and receiver/drier unit, and the low-pressure side is the air conditioning evaporator. The dividing point between high and low pressure cuts through the compressor and the expansion valve. The following section discusses in detail each piece of the HVAC system (see Figure 2). An evaporator is a heat exchange device in the refrigeration cycle. The liquid refrigerant, coming out of expansion value and entering into the evaporator, is at lower temperature and lower pressure.

On passing through the evaporator coils refrigerant absorbs the heat from the air that is blown through the coils and gets converted to low temperature, low pressure vapor. The liquid refrigerant is made to flow from the bottom to the top of the evaporator coils to ensure that liquid refrigerant boils before it leaves the evaporator coils. The tasks performed by the evaporator can be summarized as follows: The air blown by the blower in turn gets cooler, on transferring the heat, and is passed into the cabin through the vents. Since air conditioning evaporator provides the cooling by absorbing the heat from the surrounding medium, it could serve dual purpose when placed very close to dashboard of vehicle. It absorbs the heat from the air that is passed through it and also absorbs heat from inside the vehicle to maintain the required temperature.The compressor absorbs vapor refrigerant from the suction line and compresses the vapors to high superheat vapor. The temperature of the vapor is normally two and a half times higher than the temperature of the outside air.
