Description:TECHNICAL FIELD
The present disclosure relates to an air conditioner, more particularly relates to an air conditioner comprising an efficient heat exchanger design enabling the air condition to be smaller in size and portable.
BACKGROUND
Air conditioning system help regulate the temperature and the humidity of the air within a close premises. Further the newer models of air conditioners are being adopted to purify air by filtering pollutants, bacteria, pollen, dust from the ambient thereby providing comfort to the people residing with air-conditioned premises.
The air conditioner works on a principle of extracting heat from a closed cabin and rejecting the heat into the ambient environment or the heat sink. The air conditioner cycle can be broadly explained as vapor compression and refrigeration cycle that is performed in two distinct parts in the air conditioner, i.e., the evaporator section, and the condenser section.
Further different type of air conditioners may have different system architectures for instance the window air conditioner has a single cabinet with both evaporator and condenser section mounted within the frame such that the evaporator section is inside the room or the cabin area and the condenser is outside the cabin area.
In another system architecture the air conditioners may be split type air conditioner. In the split air conditioning system, the evaporator section and the condenser section are two separate entities which are connected by refrigerant lines. The evaporator section is placed within the room and the condenser section is placed outside the room.
However, the wall/window mounted air conditioner and split air conditioners are bulky in size and weight and require high power for operation. The split air conditioners however provide considerable advantages as compared to the wall/window mounted air conditioners by providing multiple evaporators and centralized condenser unit outside the room depending on the heat load of the target volume. The window air conditioners also require support structure and have high noise and vibrations because the compressor and fans of condenser unit are in very close proximity to the evaporator section.
To overcome above limitation air conditioner may be designed to use Peltier effect. The Peltier based air conditioner may comprise of Peltier chip. The Peltier effect uses a temperature drop in one section of the Peltier chip and the rise in temperature in another section of the Peltier chip once an electric potential is applied across the terminals of the Peltier chip for the cooling effect without the need for refrigerant fluid. Further the Peltier based portable air conditioners have no such compressor and refrigerant lines and thus provide lightweight and portable architecture. However, the Peltier based air conditioner have extremely low on Coefficient of Performance making them inefficient in cooling applications wherein the heat load is high.
Thus, the air conditioner architecture as disclosed are based on fundamental design having the evaporator section integrated inside the room and the condenser section is mounted outside in the ambient. Hence, there is a need in the art, to have an air conditioner that is portable and can efficiently cool a room. Further there is a need in the art to eliminate the refrigerant lines/tubes to reduce leakage in refrigerant tubes and pressure losses in refrigerant flow.
OBJECTS OF THE INVENTION
The principal object of the present disclosure is to provide a compact, lightweight, and multipurpose air conditioning system.
Another object of the present disclosure is to provide a heat exchanger configured to allow the air conditioner to be plugged in multiple applications.
Yet another object of present disclosure to provide a wash deck to be developed to provide increased turbulence for the particulate material flowing over the surface of the wash deck for best possible cleaning effect.

In accordance with an exemplary embodiment a portable apparatus for cooling a room. The portable apparatus may comprise a multiphase heat exchanger, fans and a compressor with refrigerant flow through the thermal circuit based on the vapor compression and refrigeration cycle. The apparatus may comprise two ports, one port through which cold air is released into the room and has a specific volume/body ratio, based area required to be cooled, and whereas the other port is the return port configured to recirculate air back into the apparatus. Further the apparatus may comprise high rpm axial fans. The axial fans may be placed in proximity to the multiphase heat exchangers, thereby ensuring high value of heat transfer between the refrigerant and the air through the heat exchanger thereby leading to high thermal efficiency of the system. Further phase change of refrigerant occurs within the multiphase heat exchanger assembly leading to the cooling effect within the localized region of the heat exchangers. The fan placed in cold region of heat exchanger channels the working air through the cold section of the heat exchanger leading to temperature drop of air and thus supply this cool air into the target volume.

During the flashing process, the refrigerant evaporators taking energy from the internal energy lading to severe drop in temperature. The subcooled refrigerant has very low temperature and pressure and it is passed into an evaporator 4. The evaporator 4 is further mechanically connected to the condenser 3 to enable flow of refrigerant. Thermal insulation is provided between the evaporator 4 and condenser 3 to avoid heat influx from the hot condensing section into the cold evaporator section 12.
