Definitions

• the present invention generally relates to a hybrid air-conditioning module. More particularly, the present invention relates to a system and method for providing effective and ef- ficient air conditioning using one or plurality of hybrid capillary panel(s) is/are installed based on the requirement, area and type of air-conditioning.
• the analogy derived for the invention is from the shadow of tree, where in the water from the earth reaches the leaves which will absorbed the heat from above and offering the cool shade to the person standing below. In this process no air is blown, no air is sucked. Only the water content in the leaf is being fed by the earth through roots to stem, stem to branches and then to leaves. The heat from above will be absorbed by the leaves by evaporating the water in the leaf, hence keeping the space below at lower temperatures.
• plastic capillary tube mats for cooling and heating rooms and/or water baths (DE 197 51 883 C2), which amongst other things, also contain a spiral- shaped, wound plastic capillary tube mat.
• Characteristic of this construction is a foil disposed between the capillary tube mats, which have protuberances, by means of which pas- sages are formed. As one flow of substance flows through the capillary tube mat, the second flow of substance is directed through the passages formed by the foil. From a hydraulic point of view, the high pressure loss which occurs due to the flow resistance on the foil is a particular disadvantage. From a thermodynamic point of view, the solution based on the spiral- shaped winding has various disadvantages.
• the foil lies against the capillary tubes, which means it is not possible to produce a free flow round them, thereby reducing the external coefficient of heat exchange.
• the result of an arrangement with a capillary mat with a single inlet for the liquid flow is a cross-counter flow guide system with a low proportion of counter-flow due to the fact that the secondary flow of substance is axially directed. If opting for several inlets, the pressure loss in the capillary tube mat rises sharply.
• the temperature of the externally directed flow of substance is- not uniform across the cross-section of the heat exchanger, which can be a particular disadvantage at the outlet.

• FIG. l is a diagram 100 depicting an overview of a system for providing effective and efficient air conditioning.
• the system includes a compressor 102 and a condenser 101.
• the compressor has suction and discharge ports.
• a number of hybrid capillary panel units 104 run between the compressor suction port and the condenser.
• One or more valves block and unblock at least one of the panel units.
• valves may be a solenoid valve 104.
• a switching controller may be coupled to the valves and may be programmed to control the duty cycle and frequency of the valves.
• a temperature controller may be coupled between the compressor and the switching controller. Additionally, the system may build intelligence and implement PWPFM (Pulse width Pulse Frequency Modulation) controller to switching cir- cuit.
• PWPFM Pulse width Pulse Frequency Modulation
• the hybrid capillary panel units 104 are equipped with respective solenoid valve 103, wherein the hybrid capillary panel units 104 are connected be- tween the suction line and discharge line from the compressor (not shown).
• FIG.3 is a. schematic representation of hybrid capillary panel unit.
• the hybrid capillary panel units 104 are installed with suctions fans on the standard suspended ceiling.
• FIG.4 a schematic representation of control system controlling the solenoid valves.
• plurality of solenoid valves (103a, 103b, 103c, 103d) are connected with temperature controller 105 along with switching controller 106 and which is further connected to the com- pressor and fan controller 107 which controlling the activity of the solenoid valves.
• the required frequency of modulation may be quite long. If the criterion for opening and closing a valve is a direct variation in indoor temperature, as described for the simpler controller cases, the thermal inertia of the cooled space— the house— may result in many minutes or more of operation with one or another valve combination before temperature changes enough to drive a change in valve open/close states. Also note that as more valves are added to the system and more system capacity increments become available, the required frequency of modulation decreases. This could be much longer than the exemplary 100 seconds identified above
• the invention can be applied plaster/drywall or drop ceiling, existing wall ceiling and floor surfaces and each room can be setup having a separate zone and can be used in existing and new construction, residential and commercial areas.
