FIELD OF INVENTION
This invention generally relates to air conditioning systems and more particularly to a system for controlling heating, ventilation and air conditioning in a closed environment.
BACKGROUND
A split and multi-split air conditioning system is the conventional system for controlling temperature in residential and commercial applications. The split air conditioning is a one-to-one system consisting of one evaporator unit connected to an external condensing unit. The indoor evaporator unit absorbs heat from the surrounding air while the outdoor condensing unit transfers the heat to the environment. A multi-type air conditioning system operates on the same principles as the split type air conditioning system however in the former case, there are multiple evaporator units connected to one externa! condensing unit. The same is applicable for reverse flow viz. Heat Pump.
Variable refrigerant, flow (VRF) is an essentially large-scale version of the ductless mini-split air conditioning systems. A conventional VRF system includes an outdoor condensing unit and multiple indoor evaporator units. The outdoor unit typically comprise of compressor and condenser, while the indoor unit includes expansion valve, heat exchangers, fan etc. The VRF system controls the amount of refrigerant flowing to the multiple evaporators, enabling the use of many evaporators of differing capacities and configurations connected to a single condensing unit. Such arrangement provides an individualized comfort control, and simultaneous heating and cooling in different zones.

limited usage of evaporator per se. The other existing inventions that mention about remote evaporator are those where the movement of the evaporator is possible only with the movement of the partition walls. In such cases, the evaporator unit is fixed to the partition wall. The limitation with this system is the unwanted movement of the partition wall as well as the non-usability in systems where walls are fixed.
Hence there is a need for an air conditioning system that can overcome one or more of the problems as set forth above.
SUMMARY OF THE INVENTION
According to an embodiment of the invention, an air conditioning system for an enclosed space is disclosed. The enclosed space have a plurality of walls, a ceiling and a floor arranged in a way so as to form.the enclosed space. The air conditioning system includes a refrigeration unit. The refrigeration unit is mounted on one of the walls external to the enclosed space. The air conditioning system further includes at least one heat exchanger unit. The heat exchanger unit . is in communication with the refrigeration unit and is movably attached on a fixed structure inside the enclosed space. The movement of the heat exchanger unit on the fixed structure may be configured in such a way that the heat exchanger unit moves freely within the enclosed' space without being detached from the fixed structure.

The enclosed space 102 have a plurality of walls connected to each other side to side, a ceiling on the top and a floor at the bottom. According to an embodiment, the enclosed space 102 may be a room. According to another embodiment, the enclosed space 102 may be a container. According to yet another embodiment, the enclosed space 102 may be any closed area such as, but not limited to, a chamber, a hall, an auditorium etc. The enclosed space 102 may include at least one partition 118 to divide the enclosed space 102 into two separate smaller enclosed spaces 110, 112, 114. According to an embodiment, the partition 118 may be a fixed wall. According to another embodiment, the partition 118 may be a removable wall. The temperature in the enclosed space 102 is controlled by an air conditioning unit. The air conditioning unit includes a refrigeration unit 104 and at least one or more heat exchanger units 106. According to an embodiment, the air conditioning system 100 may be operated to cool the enclosed space 102. For cooling the enclosed space 102, the heat exchanger unit 106 acts as a condenser/ gas cooler and reduces the temperature of the enclosed space 102. According to another embodiment, the air conditioning system 100 may be operated to heat the enclosed space 102. For heating the enclosed space 102, the heat exchanger unit 106 acts as a heat pump to increase the temperature of the enclosed space 102. The heat exchanger 102 acts as the heat pump when the refrigerant flow in the air conditioning system 100 is reversed to the flow in case of cooling. According to an embodiment, the refrigeration unit 104 is mounted external to the enclosed space 102. According to another embodiment, the refrigeration unit 104 is mounted on the external side of the wall of the enclosed space 102. The refrigeration unit 104 is connected to one or more of heat exchanger units 106 through multiple refrigerant lines 116 a*E= S^&olse'd^Feifr■] ~geran Mnow* e lr£u i t^Th^air^eortd i ti on i hg-^yste nrH 0 O^fdTther" i nc" IOT esrair^i=i

arrangement for moving the evaporator heat exchanger units 106 within the enclosed space 102.
Figure 3 illustrates an isometric view of the air conditioning system 100 in the enclosed space 102 according to an embodiment of the invention. Figure 3 shows the movement of one of the heat exchanger unit 106 from an initial position in the enclosed space 110 in figure I to another position in the enclosed space 114 in figure 3. The movement of the heat exchanger unit 106 within the enclosed space 102 is on a fixed structure 108. According to an embodiment, the Fixed structure 108 may be a guiding assembly. The heat exchanger unit 106 may be arranged on the fixed structure 108 in such a way that the heat exchanger 106 independently moves within the enclosed space 102. According to an embodiment, the Fixed structure 108 may be provided in proximity to the ceiling above the partitions I 18 for the heal exchanger unit 106 to move freely from one smaller enclosed space 1 10, I 12, 114 to another smaller enclosed space 110, 112, 114. According to another embodiment, the partitions 118 may be provided with a gap for the heat exchanger unit !06 to move freely from one smaller enclosed space 110, 112, 114 to another smaller enclosed space 110, 112, 114 through the gap. The fixed structure 108 may also be provided on the side wall of the enclosed space 102 to allow the heat exchanger unit 106 to move horizontally on the walls. The heat exchanger unit 106 maybe suitably moved to any of the smaller enclosed spaces 110, 112, 114 as per load and flow requirements throughout the enclosed space 102.
Figure 4 illustrates an isometric bottom view of the fixed structure 108 according to an embodiment of the invention. The fixed structure may be the guiding assembly 108 for the

embodiment, the movement of the evaporator unit 106 on the guiding assembly may be

achieved by any of the systems such as, but not limited to a mechanical system, a hydraulic system, an electrical system, a pneumatic system, a magnetic system. According to an embodiment, the movement of the evaporator unit 106 on the guiding assembly may be actuated manually. According to another embodiment, the movement of the evaporator unit 106 may be actuated automatically.
Figure 5 illustrates an isometric view of the air conditioning system 100 and partial closed space 102 according to an embodiment of the invention. A single heat exchanger unit 106 may be placed between two smaller enclosed spaces ! 10, 112 on the fixed structure 108 to control the temperature of both the enclosed spaces 110, 112 simultaneously, when the temperature in the enclosed space 110 reaches desired temperature, the heat exchanger unit 106 may slide to the other enclosed space 112. Upon reaching the temperature requirement of both the enclosed spaces 110, 112, the heat exchanger unit 106 may return to its centre position thereby providing uniform air conditioning. The movement control of the heat exchanger unit 106 may be programmed according to the end user requirement. According to an embodiment, a user may enter the desired location coordinates in the computer and the heat exchanger units 106 may automatically move to the exact position within the enclosed space 102. According to another embodiment, the user may move the heat exchanger units 106 to the desired location using a joystick or a switch. The heat exchanger unit 106 rearrangement may enable uniform cooling or heating to the required area within the enclosed space 102, efficient energy management and reduced load on the compressor.
A refrigerant may flow between the refrigeration unit 104 and the heat exchanger units 106 :■■■- ,,... th roygh-jt hte-Fe fri geran t-l ifteFJ-L6^Th e-re-fr igera n t4i ne-U-form a^be^-hose.~.Acco rd i ng-to-an— embodiment the hose 116 may be a flexible hose or an extendible hose or a stretchable hose
