FIELD OF INVENTION
The present invention relates to air conditioner. Specifically the present invention relates to process of dissipation of heat generated in compressor of split air conditioner. More particularly the present invention relates to the process of using of cold condensate formed in the evaporator to dissipate the heat generated by compressor.
BACKGROUND
A split air conditioner as illustrated in Figure 1 uses vapor compression refrigeration system which has four essential components. They are compressor 1, condenser 2, expansion valve or throttling device 3 and an evaporator 4. Refrigeration may be defined as removing the heat and lowering and maintaining the temperature well below its ambient temperature of an enclosed space. A refrigerant medium 5 is a liquid which is being circulated in the components of closed cycle vapor compression system which absorbs the heat and transfers it to the ambient.
Compressor is observed as the heart of the vapor compression system that compresses the vapour refrigerant that actually comes out from the evaporator. Compressor is the only part which generates heat energy because of the electrical work input given for compressing the refrigerant. The refrigerant pressure increases and also the temperature because of the compression. The heat obtained by the refrigerant is then cooled in an air cooled condenser where the temperature of the refrigerant reduces and keeps the pressure at same level. The refrigerant is then routed to an expansion valve where it undergoes an abrupt reduction in pressure. Due to Joule Thomson effect, the temperature is reduced drastically. This low temperature refrigerant is then circulated in the coils of evaporator tubes where it absorbs the heat of the medium to be cooled and maintained.
Apart from the actual refrigeration system, the air conditioners produce condensate because of the moisture contained by the air stream which flows over the surface of the evaporator. The cold condensate 6 without utilizing its low temperature for sub-cooling of the refrigerant, it is discharged to the environment 7. Hence it is required to utilize the low temperature condensate to extract the unwanted heat generated.

The temperature of the refrigerant from the compressor can be measured by placing an insulated thermistor or thermocouple on the discharge line about 3 to 4 inches from the compressor. The discharge temperature is a measure of the superheated refrigerant’s vapor temperature. Since the compressor’s discharge temperature is a superheated vapor temperature, a pressure/temperature relationship does not exist, and a pressure gauge cannot be used for its measurement. Pressure gauges can only be used for a pressure/temperature relationship when a saturation temperature (evaporating and/or condensing) is needed.
The most common types of refrigeration systems use the reverse-Rankine vapor-compression refrigeration cycle, although absorption heat pumps are used in a minority of applications.
Cyclic refrigeration can be classified as:
1. Vapor cycle, and
2. Gas cycle
Vapor cycle refrigeration can further be classified as: i) Vapor-compression refrigeration ii) Sorption Refrigeration
a. Vapor-absorption refrigeration
b. Adsorption refrigeration
The vapor-compression cycle is used in most household refrigerators as well as in many large commercial and industrial refrigeration systems.
In this cycle, a circulating refrigerant such as Freon enters the compressor as a vapor. The vapor is compressed at constant entropy and exits the compressor as a vapor at a higher temperature, but still below the vapor pressure at that temperature. The vapor travels through the condenser which cools the vapor until it starts condensing, and then condenses the vapor into a liquid by removing additional heat at constant pressure and temperature. The liquid refrigerant goes through the expansion valve (also called a throttle valve) where its pressure abruptly decreases, causing flash evaporation and auto-refrigeration of, typically, less than half of the

liquid which results in a mixture of liquid and vapor at a lower temperature and pressure. The cold liquid-vapor mixture then travels through the evaporator coil or tubes and is completely vaporized by cooling the warm air (from the space being refrigerated) being blown by a fan across the evaporator coil or tubes. The resulting refrigerant vapor returns to the compressor inlet.
The above discussion is based on the ideal vapor-compression refrigeration cycle, and does not take into account real-world effects like frictional pressure drop in the system, slight thermodynamic irreversibility during the compression of the refrigerant vapor, or non-ideal gas behavior, if any. Vapor compression refrigerators can be arranged in two stages in cascade refrigeration systems, with the second stage cooling the condenser of the first stage. This can be used for achieving very low temperatures.
The main difference with absorption cycle, is that in adsorption cycle, the refrigerant (adsorbate) could be ammonia, water, methanol, etc, while the adsorbent is a solid, such as silicone gel, activated carbon, or zeolite, unlike in the absorption cycle where absorbent is liquid.
The reason adsorption refrigeration technology has been extensively researched in recent 30 years lies in that the operation of an adsorption refrigeration system is often noiseless, non-corrosive and environment friendly.
GAS CYCLE
When the working fluid is a gas that is compressed and expanded but doesn't change phase, the refrigeration cycle is called a gas cycle. Air is most often this working fluid. As there is no condensation and evaporation intended in a gas cycle, components corresponding to the condenser and evaporator in a vapor compression cycle are the hot and cold gas-to-gas heat exchangers in gas cycles.
The gas cycle is less efficient than the vapor compression cycle because the gas cycle works on the reverse Brayton cycle instead of the reverse Rankine cycle. As such the working fluid does not receive and reject heat at constant temperature. In the gas cycle, the refrigeration effect is equal to the product of the specific heat of the gas and the rise in temperature of the gas in the

low temperature side. Therefore, for the same cooling load, a gas refrigeration cycle needs a large mass flow rate and is bulky.
Because of their lower efficiency and larger bulk, air cycle coolers are not often used nowadays in terrestrial cooling devices. However, the air cycle machine is very common on gas turbine-powered jet aircraft as cooling and ventilation units, because compressed air is readily available from the engines' compressor sections. Such units also serve the purpose of pressurizing the aircraft.
The present invention provides a solution for cooling the compressor with the cold condensate collected in the evaporator, thus it increases the efficiency of compressor and also the said invention reuses the waste cold water instead of using fresh water.

DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO ACCOMPANYING DRAWINGS:
A split air conditioner uses vapor compression refrigeration cycle including a compressor 1, a forced circulating air condenser 2, an expansion or throttling device 3 and an evaporator 4. All of this equipment is combined in closed cycle where the refrigerant 5 is circulated. When the refrigerant 5 at low temperature flows inside the evaporator tubes, the moisture condenses from the air stream which flows over the evaporator surface since the refrigerant absorbs the heat contained by air stream, thus forms cold condensate 6. In the present invention the said split air conditioner is attached with a jacket 8 and a thermal insulated pipe 9 for cooling the compressor 1 where the refrigerant is sub cooled before it is sent in to the condenser.
With reference to figure 2, the process of the present invention comprises of attaching the said compressor 1 with jacket 8 wherein the said jacket is an open or closed jacket and is attached at the outer surface. The compressor 1 is the only part of the air conditioner where heat is generated and because of it the refrigerant temperature shoots up, therefore the said jacket 8 contains one or more openings at the bottom for hot condensate 10 discharge produced by cooling the hot compressor.
Another step of the said process, to reduce the temperature of the refrigerant 5 cold condensate 6 is used. The split air conditioner produces the condensate in the evaporator due to the moisture present in the air, thus this cold condensate is used to cool the compressor by fixing thermal insulated pipe 9 at the discharge outlet of the said evaporator.
One another step of the said process is allowing the said cold condensate to flow from the evaporator to the said jacket through the thermal insulated pipe. The said cold condensate from the thermally insulated pipe flows either by gravity to the annular space between compressor and jacket or sprayed over the outer surface of the compressor by pump.

The next step of the said process is discharging the hot condensate 10 formed in the jacket of the compressor to the ground by means of the outlet drain pipe 11 attached at the bottom part of the jacket.
In the present invention the cold condensate 6 formed in the evaporator is utilized to dissipate the heat generated by compressor 1. Due to the above heat dissipation in compressor, the temperature of the refrigerant is also lowered thereby enhances the efficiency of the split air conditioner.
