DETAIL DESCRIPTION OF INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS OF THE PREFERREDEMBODIMENTS:
[0043] While the embodiments of the disclosure are subject to various modifications and alternative forms, a specific embodiment thereof has been shown by way of example in the figures and will be described below. It should be understood, however, that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternatives falling within the scope of the disclosure.
[0044] The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusion, such that a device, system, assembly that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such system, or assembly, or device. In other words, one or more elements in a system or device proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or device.
[0045] The invention is related to the system and the method of heating and cooling a room using a heat transfer medium called a green fluid that is a combination of water and a non-refrigerant.
[0046] Referring to Fig. 1, a first heat exchanger (201) is disclosed. The first heat exchanger (201) has multiple HDPE piping coils (101) that are placed in multiple layers, vertically. The HDPE piping coils (101) and fixtures optimize on material costs. The HDPE coils (101) are highly flexible and durable and are able to be bent on site to a radius twenty-five times the small pipe diameter, providing major cost savings, when compared to the other pipe systems. That is the reason, the HDPE piping coils (101) are placed beneath the earth (204) in the system (200).
[0047] Referring to Fig. 2, the system (200) for heating and cooling a room (203) is disclosed. The room (203) is not limited to one shape. The system (200) switches on as a heating system when the weather is cold and a cooling system when the weather is hot, providing comfort and control to the user/person present in the room (203).
[0048] The operating principle is based on coupled performance of two disjoint heat exchangers present in the system (200). The first heat exchanger (201) is embedded in the earth’s surface near to the room (203). The first heat exchanger (201) is not exposed to elements of nature and the exterior surfaces of HDPE is not prone to erosion. Due to continuous flow in the interior surfaces, the possibility of bio-fouling is present, is prevented by the anti-fouling properties of the non-refrigerent fluid.
[0049] The first heat exchanger (201) is bulky in construction and is placed in a 10-foot pit dug under the surface of earth (204). It takes the shape of several bends of HDPE pipe coils (101) placed in multiple layers, vertically. The design of pipe lengths, diameter and flow paths have been numerically simulated for ensuring proper flow and good thermal performance.
[0050] The soil is refilled and compacted into the voids between the first heat exchanger (201) HDPE pipe coils (101) bends. Support spacers are placed between multiple layers to prevent bending or breaking due to soil loads.
[0051] The second heat exchanger (202) is provided inside the room (203) and is located above the surface of the earth (204). The second exchanger (202) is a fin-based radiative heat exchanger.
[0052] The green fluid exits from the second heat exchanger (202) and enters into the first heat exchanger (201) which is present in the soil present under the earth (204) to exchange heat with the soil.
[0053] The sensors (207) are placed inside the room (203) and underground to give information related to temperature and humidity. A flow meter (208) connects the first heat exchanger (201) and the second heat exchanger (202). The flow of the green fluid is measured using the flow meter (208) and depending upon the requirement of the user, it can be altered by commands to sensors (207) for valve operation.
[0054] Referring to Fig. 4, The first heat exchanger (201) and the second heat exchanger (202) are coupled to one another by pipes to provide climate specific performance to the indoor space and the path taken by the green fluid is disclosed. A pipe from fluid supply tank (209) is placed on the ground supplies fluid at the entry of first heat exchanger (201) in a T-joint. The green fluid flow from exit of first heat exchanger (201) becomes input supply fluid at the entry of the second heat exchanger (202) and at the exit of the second heat exchanger (202) it connects with the entry of the first heat exchanger (201) for exchanging the fluid continuously and cyclically. The connections are made at interfaces with due pipe reducers. The fluid supply tank (209) is flexibly connected and can be cleaned during regular maintenance or performance monitoring.
[0055] The heat transfer medium flowing is a green fluid and is present in the fluid supply tank (209). The green fluid flows through both the first heat exchanger (201) and the second heat exchanger (202) cyclically to exchange the heat. In the room (203), the heat exchange is between the air in the room (203) and green fluid. Depending on the prevailing weather conditions, this exit temperature condition of green fluid provides cool or hot air in the room (203).
[0056] In summer, the heat is exchanged from hot air in room (203) to cooler green fluid through the second heat exchanger. The heated green fluid exits the second heat exchanger (202) and enters the first heat exchanger (201) and loses heat to the soil in the earth (204) through the first heat exchanger (201). This occurs in reverse during winters. The heat is exchanged through soil because the temperature of soil at 10 feet deep is uninfluenced by the above-earth ambient conditions.
[0057] A fan (206) is placed in the room (203) for circulating the air. The fan (206) includes a fine air filter at its exit and is placed at the window of the room (203). The fan (206) creates a ventilated air flow in the room (203) to exchange heat from the second heat exchanger (202). A pump (205) is provided in the system (200) that is connected to the first heat exchanger (201) and the second heat exchanger (202) to pump (205) the green fluid from the first heat exchanger (201) to the second heat exchanger (202).
[0058] A plurality of sensors (207) are placed at multiple locations inside the room (203) and in the soil of the earth (204). The sensors (207) are IOT enabled devices that provide temperature and humidity information. The sensors (207) also ensure the adequate control to obtain hot or cold air in the room (203), depending on seasonal conditions. The user gets data of the performance of first heat exchanger (201) and the second heat exchanger (202) over a user interface such as a smart phone or laptop.
[0059] Referring to Fig. 3, the method (300) illustrates the exchange of the heat between a first heat exchanger (201) present beneath the earth (204) and a second heat exchanger (202) using a green fluid present inside a room (203). The first step (301) is to exchange the heat present inside the room (203). The hot air enters the second heat exchanger (202) with the aid of the fan (206). The hot room air transfers the heat to the cooler green fluid flowing inside the second heat exchanger (202) and the green fluid gets heated up. The heated green fluid exits the second heat exchanger (202) by means of the pump (205) and enters the first heat exchanger (201).
[0060] Further, in the second step (302) the heated green fluid loses its heat to the soil in the earth (204) and gets cooled down. The green fluid then enters the first heat exchanger (201) again with the aid of the pump (205) and the cycle continues.
[0061] The method (300) explained above acts in reverse condition during the winter times when the room (203) needs to be heated instead of getting cooled. In the winter times, as the ambient surrounding air is cool, the cold air gets heated by the green fluid that has a higher temperature condition pertaining to the higher temperature of the soil below the earth (204). Since, the temperature of the soil inside the earth (204) never changes, the soil heats the green fluid up and the heated green fluid after passing through second heat exchanger (202) is used to heat the room (203).
[0062] The exit temperature condition of the green fluid leaving the first heat exchanger (201) determines the extent to which the cool air or hot air is provided in the room (203). The sensors (207) provide a quantitative value to this level of cooling or heating comfort attained by way of temperature and humidity display.
[0063] The table below provides time based details of data from the sensors (207) and acts as an operating guide for user, to change green fluid flow rate and achieve better room (203) comfort.

TECHNICAL ADVANTAGES
[0064] With the help of the solution as proposed herein in the context of the present disclosure, a low cost heating and cooling system is obtained that can be used in small, medium and big spaces.
[0065] The present disclosure further provides that the maintenance of the sytem is easy and minimal. Further, it’s operational life is high due to absence of wear and tear of machine components.
