Specialists have worked hard in providing the necessary tips of troubleshooting due to the many concerns that have been raised by different people on the 944 air conditioning systems. These systems have nearly the same components with almost similar functions which is known to AC repair company Eugene OR.
When a problem has been detected on any 944 A/C systems, a person is required to follow two processes so as to determine the problem in this system. The first step one can resort to is the physical step by step process of component replacement in the system, subsequently replacing the non-functional component. The person might also decide to use A/C gauges to carry out specific problem tests.
A proper understanding on the functioning of this automobile A/C is important before any attempt of any troubleshooting. There are two types of A/C systems in automobiles, depending on what is used in regulation of temperature and the pressure of this liquid. The first type utilizes the orifice tube while the second type uses an expansion valve, as in 944 A/C systems.
The first part of any air conditioning system comprises the compressor, a component that increases both the pressure and temperature of its refrigerant by compressing it. The hot refrigerant in liquid form then enters the condenser that is connected to a radiator. The radiator facilitates heat loss which enables the gas to condense to liquid form.
In the first system, the refrigerant in liquid form enters the orifice tube immediately after the condenser. The decrease in pressure of the refrigerant is usually equivalent to that tube internal pressure. This enables the orifice tube to effectively regulate the pressure at the suction with the aid of a clutch to rotate the compressor.
The expansion valve of AC has a receiver-drier which is significant in separation of moisture from the refrigerant so as to improve its heat exchange capacity. The moisture free refrigerant is usually passed through what is referred to as the expansion valve so as to regulate the suction pressure, one that is meant to normalize the conditions of this device.
The expansion valve and the orifice tube both play an important and similar role of reducing the temperature of this refrigerant by dropping the pressure. These two expansion devices lower the temperature of this refrigerant by reducing its values. This basically shows the homogeneity in these functions of both devices.
The other important part of both air conditioning systems is the evaporator, which allows hot air from the passengers compartment through one part of its numerous coils. The cooler refrigerant passes through the other part of these coils. These movements facilitate the loss of heat by the hot air, converting it to a lower temperature gas.
The orifice tube system usually has an accumulator placed between the compressor suction and the evaporator. The accumulator has the same function as the receiver-drier which absorbs moisture, only that it even removes any refrigerant that has not evaporated which leads to liquid lock from the rotations of the compressor.
There are many guides of troubleshooting the different air conditioning systems in the market. These guides give important information on the different diagnoses, their causes and their possible solutions. To effectively understand these guides, one requires the general knowledge of air conditioning systems outlined above.
