Description

[0001]TITLE OF THE INVENTION: ECO-CLIMATE CONDITIONING SYSTEM CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY The present application claims priority from the Indian patent application having application number 202321064950, filed on 27 November 2023, incorporated herein by a reference. TECHNICAL FIELD The present invention relates to the field of a conditioning system. More particularly, the present invention relates to an eco-climate air conditioning system configured to provide a cooling effect by optimizing a standard required refrigeration. BACKGROUND This section is intended to introduce the reader to various aspects of art, which may be related to various aspects of the present disclosure that are described or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements in this background section are to be read in this light, and not as admissions of prior art. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology. Air conditioning systems are widely used in industrial buildings, residential buildings, commercial complexes, medical facilities, and many other utilities. The need for air conditioning is highly demanded for the comfort of people working within a larger cooling areas or spaces. Therefore, huge capacity of air conditioning systems is needed to be installed for cooling of such larger areas. To encompass such high demand of the air conditioning, it is required to use energy efficient and environment friendly air conditioning solutions. Currently, the air conditioning industry has failed develop a solution addressing the energy consumption problem of air conditioning system required of larger cooling areas. The energy consumption by present air conditioning systems leads to cause significant effect on environment, which can become more harmful in upcoming time. The balance between the energy consumption and cooling requirement needs to be achieved to mitigate such effects on environment. Traditional air conditioning systems are known to consume a significant amount of energy coming from fossil fuels and renewable sources. The large part of the energy produced in the world belongs to the fossil fuels. These fossil fuels are limited in nature, hence production of energy from such fossils has certain limitations and disadvantages in longer run. Therefore, excessive consumption of energy by traditional air conditioning systems indirectly contributes to adverse factors such as greenhouse emissions and climate change. Further, the traditional air conditioning systems are highly energy-intensive, which leads to high electricity bills. Furthermore, the cooling requirements of larger industries or commercial buildings remain high during summer season. Such requirement increases strain on power grids during peak seasons. In addition, the conventional air conditioning systems lacks to align with goals of sustainability and reducing their carbon footprint. Nowadays, the cooling requirement of larger cooling areas is fulfilled by installation of multiple cooling units. Further, the use of multiple cooling units for covering such larger areas can lead to excessive wastage of energy. Such wastage of energy is not only costly but also leads to unsustainable operation. More specifically, the arrangement of multiple cooling units for larger area leads to increasing purchase cost, installation cost, installation time, maintenance cost, and huge energy consumption. Also, there is chance of failure of one or more cooling unit out of multiple cooling units, which can again lead to inefficient cooling. Further, such inefficient cooling can increase load on other cooling units causing more consumption of energy. Therefore, a cooling arrangement using lesser energy to provide multiplied cooling effect is required to be developed. The conventional air conditioning system facilitates limited control over the cooling operation. Such limited control makes it challenging to meet individual or process-specific requirements related to cooling. This lack of customization within the traditional air conditioning systems results in discomfort for occupants or suboptimal conditions for various applications. This can arise unnecessary consumption of the energy without consideration of specific cooling requirement with respect to the ambient conditions. Therefore, there is need to develop an air conditioning system having multiple controlling modes for controlling the cooling operation with respect to different ambient conditions, cooling requirements, and atmospheric seasons etc. In light of the above stated discussion, there exists a need of an improved air conditioning system to overcome at least one of the above stated problems.

Furthermore, the first chamber (102) is connected to the second chamber (104) via one or more first supply duct (114a) and one or more first return duct (116a). Additionally, a combination of the first chamber (102), the sub-chamber (102a), and the second chamber (104) is configured to provide cooling effect to a cooling space (120). Further, the second chamber (104) is connected to the cooling space (120) via one or more second supply duct (114b) and one or more second return duct (116b). In an example embodiment, the sub-chamber (102a) may be a sub-compartment of the first chamber (102). Further, the first chamber (102) and the sub-chamber (102a) may be connected by a common wall.

Further, the sub-chamber (102) may be also equipped with the one or more first cooling unit (112) configured to cool a space around the one or more heat rejecting device (110b). In one example, the sub-chamber (102a) may be an optional structure. More specifically, the outdoor unit (110) including the one or more compressing device (110a), and the one or more heat rejecting device (110b) may be placed in an open environment without the sub-chamber (102a). Further, the one or more first cooling unit (112) configured to cool the outdoor unit (110) may be placed in the open environment without the sub-chamber (102a). Furthermore, the provision of the sub-chamber (102a) may be required only in experimental setup of the air conditioning system (100). Moreover, the refrigeration loop (118) may be also formed in absence of the sub-chamber (102a). Now referring to figure 1, the one or more compressing device (110a) of the refrigeration loop (118) may compress the high temperature refrigerant coming from the one or more heat absorbing device (106) to a high pressure. Further, the high pressure and high temperature refrigerant may enter the one or more heat rejecting device (110b). Furthermore, the one or more heat rejecting device (110b) may be reject the heat from the refrigerant to an outside space formed by the sub- chamber (102a). Moreover, the one or more heat rejecting device (110b) may turn the refrigerant into liquid state with drop in temperature of the refrigerant. More specifically, the low temperature refrigerant may leave the one or more heat rejecting device (106) in the form of liquid condensate. In one another example embodiment, the low temperature liquid refrigerant from the one or more heat rejecting device (110b) may enter the one or more heat absorbing device (106) in the first chamber (102). Further, the one or more heat absorbing device (106) may be configured absorb heat from an outside space formed by the first chamber (102). Furthermore, the action of heat absorption may result in chilling of air around the one or more heat absorbing device (106) in the first chamber (102).

Furthermore, the refrigerant from the one or more heat absorbing device (106) may enter the one or more compressing device (110a) for continuation of the refrigeration cycle. In one example, the refrigerant may flow through one or more tubing connected within the refrigeration loop (118).

Furthermore, the one or more tubing may extend from to the one or more heat rejecting device (110b) to the one or more heat absorbing device (106) for carrying the low temperature liquid state refrigerant. In one another example embodiment, the one or more heat rejecting device (110b) may be cooled by the one or more first cooling unit (112) placed within the sub-chamber (102a). More specifically, temperature of air within the outside space formed by the sub-chamber (102b) may be lowered or cooled by the one or more first cooling unit (112) below an ambient temperature. In general, a second law of thermodynamics states that the heat is transferred from higher temperature to lower temperature. In present invention, the high temperature refrigerant entering in the one or more heat rejecting device (110b) may reject heat to the low temperature air within the outside space formed by the sub-chamber (102b). Therefore, the rate of heat transfer / rejection between the refrigerant and the outside space air may effectively increase as the temperature of air lies below the ambient temperature. Thus, rate of cooling of the refrigerant inside the one or more heat rejecting device (110b) may increase, and the refrigerant may turn to cooled liquid state. Additionally, the liquid refrigerant may enter the one or more heat absorbing device (106) within the first chamber (102) from the one or more heat rejecting device (110b). Further, the increase in the rate of cooling of the refrigerant inside the one or more heat rejecting device (110b) may directly increase rate of heat absorption by the one or more heat absorbing device (106). Furthermore, the heat may transfer from the air within the outside space formed by the first chamber (102) to the low temperature refrigerant entering the one or more heat absorbing device (106) due to heat absorption. Therefore, the increase in the rate of heat absorption may increase the rate of cooling of the air within the outside space formed by the first chamber (102). More specifically, the air outside the one or more heat absorbing device (106) may get effectively cooled than due to increase in the rate of heat absorption. In yet another example embodiment, the cooled air around the one or more heat absorbing device (106) may be blown into the second chamber (104) via the one or more first supply duct (114a). More specifically, one end of the one or more first supply duct (114a) may be associated with the one or more heat absorbing device (106) in the first chamber (102). Further, other end of the one or more first supply duct (114a) may be suspended over the one or more second cooling unit (108) in the second chamber (104). More particularly, the cooled air may be blown by a blower associated with the one or more heat absorbing device (106) via the one or more first supply duct (114a).

Further, the one or more refrigeration circuit may include one or more compressor, one or more condenser, one or more cooling coil, a capillary tube, a copper tubes, or combination thereof. Moreover, the one or more second cooling unit (108) may be configured to provide cooled air to the cooling space (120) as being the independent cooling system. More specifically, the one or more second cooling unit (108) may be configured to draw air via the plurality of cooling pads drenched with cooled water to provide cooled air to the cooling space (120). In yet another example embodiment, the chilled air from the first chamber (102) may be applied on the one or more second cooling unit (108) of the second chamber (104) via the one or more first supply duct (114a). More specifically, the cooled air may be applied directly on the plurality of cooling pads of the one or more second cooling unit (108). Further, the plurality of cooling pads drenched with the cooled water may provide the additional cooling to the cooled air coming from the first chamber (102). Therefore, the application of cooled air on the plurality of cooling pads may multiply or increase the cooling output of the one or more second cooling unit (108). Moreover, the cooling output of the one or more second cooling unit (108) may be supplied from the second chamber (104) into the cooling space (120) via the one or more second supply duct (114b). In yet another example embodiment, the one or more second return duct (116b) may be configured to bring the air from the cooling space (120) to the second chamber (104). Further, the one or more first return duct (116a) may be configured to bring the air from the second chamber (104) to the first chamber (102). Furthermore, at least one of the one or more second return duct (116b) and the one or more first return duct (116a) may be provided with a suction fan. In one general example, consider 30 tons of refrigeration (TR) is required for cooling of 3000 square feet area. Therefore, cooling systems with 30 TR capacity is required to be deployed for cooling of such huge area. In an example with respect to the present invention, the one or more heat absorbing device (106) of 5 TR capacity is deployed in the first chamber (102) having 500 square feet area. Further, the one or more second cooling unit (108) of 10 TR capacity is deployed in the second chamber (104) having 1000 square feet area. Furthermore, the one or more first cooling unit (112) of 10 TR capacity is used for cooling the outdoor unit (110) within the sub- chamber (102a). Therefore, the air conditioning system (100) formed by a setup of first chamber (102), the sub-chamber (102a), and the second chamber (104) using total 25 TR capacity provides nearly 28.5 TR cooling output for cooling 3000 square feet area. Therefore, additional 3.5 TR cooling is achieved using disclosed setup of the air conditioning system (100).
