DESC:FIELD OF THE INVENTION
The present invention relates to the field of Chest Freezers. More specifically, the present invention relates to an energy-efficient refrigeration system with Anti-Frost technology to increase cooling efficiency and improve environmental sustainability.
BACKGROUND OF THE INVENTION
The problem of frost accumulation in traditional chest freezers has long been a source of inconvenience and inefficiency for both consumers and manufacturers. These freezers typically required manual defrosting, a time-consuming and bothersome task. As frost builds up within the freezer cabin, it not only consumes valuable storage space but also impedes the effective cooling of stored items.
Manual defrosting, the traditional method of dealing with frost accumulation, involves unplugging the freezer, removing stored items, and waiting for the frost to melt before manually cleaning and draining excess water. This process not only disrupts the regular use of the freezer but also poses challenges in maintaining consistent temperature levels, potentially compromising the quality and safety of stored food items.
The need for the present invention, namely anti-frost technology in chest freezers, arises from the inherent challenges and inconveniences associated with traditional freezer designs. The time-consuming and complicated nature of manual defrosting, coupled with concerns over limited storage space and compromised cooling efficiency due to frost accumulation, prompted the need for a solution. This technology addresses these challenges by eliminating the need for manual intervention and optimizing storage space and enhancing cooling efficiency and improving environmental sustainability.
OBJECTIVE OF THE INVENTION
The main objective of the present invention is to provide an advanced anti-frost system for chest freezer cabins that is more efficient, convenient, and environmentally friendly.
Yet another objective of the present invention is to optimize storage space and maximize the capacity of the freezer by preventing frost buildup within chest freezer cabins.
Yet another objective of the present invention is to minimize energy consumption by intelligently controlling the heating and cooling processes and contributing to overall energy savings.
Yet another objective of the present invention is to efficiently collect and dispose of melted frost water to eliminate the need for users to manually remove water and reduce the risk of water leakage.
Yet another objective of the present invention is to extend the operational lifespan of the chest freezers by minimizing the need for manual defrosting and maintenance by developing a reliable anti-frost system.
SUMMARY OF THE INVENTION

The frost-free Chest Freezer system includes a cooling cabin, an evaporator discharge pipe, a compressor, a compressor discharge pipe, an auxiliary coil, a valve, a drain tray, a drain pipe, a drain pan, an auxiliary coil discharge pipe, a condenser discharge pipe, a condenser, a capillary valve, a heating pipe. The cooling cabin includes an evaporator coil. The evaporator coil is placed inside the wall of the cooling cabin of the Chest freezer system. A refrigerant in the evaporator coil absorbs heat from the cooling cabin and gets heated. The evaporator coil is connected to the compressor through the evaporator discharge pipe. The refrigerant is compressed and heated in the compressor. The compressor is connected to the auxiliary coil through the compressor discharge pipe. The valve is connected to the compressor via the compressor discharge pipe. The drain tray is placed at the base of the cooling cabin to collect the melted frost water. The drain pan is placed outside the cooling cabin, the auxiliary coil is installed in the drain pan, the melted frost water from the drain tray is transferred to the drain pan by the drain pipe. The condenser is connected to the auxiliary coil through the auxiliary coil discharge pipe from the input, and the output of the condenser is connected to the evaporator coil through the condenser discharge pipe. The condenser condenses the heated refrigerant from the compressor and converts the refrigerant into a high-pressure refrigerant with lowered temperature. The capillary valve is installed on the condenser discharge pipe between the condenser and the evaporator coil. The capillary valve expands the high-pressure refrigerant from the condenser into a low-pressure, low-temperature refrigerant. The heating pipe connects the valve to the evaporator coil. The heating pipe directs the compressed and heated refrigerant toward the evaporator coil to remove frost that accumulates on the evaporator coil surface. Herein, the valve operates in cooling mode operation and the cooling cabin's temperature is brought to a predetermined level. When the temperature is attained and a predetermined time period is achieved by that time frost gets accumulates on the evaporator coil surface, the valve gets reversed, and the compressor gets connected to the evaporator coil through the heating pipe and starts operating in heating mode operation to melt the frost. When the frost is melted and the temperature and time reach below the predetermined levels, the valve reverses back to the cooling mode operation, and the compressor gets connected to the condenser via the auxiliary coil. Herein, the drain tray is strategically placed on the base of the cooling cabin, the melted frost water is collected in the drain tray and is directed to the drain pan by the drain pipe, eliminating the risk of water pooling within the cooling cabin, the frost water collected in the drain pan, the auxiliary coil is immersed in the drain pan and the refrigerant further gets cooled down, the cooled refrigerant is directed towards the condenser, the work done by the condenser to condense the refrigerant is less, reducing the load on the compressor and requirement of energy to operate the condenser is less, this increases the performance and cooling efficiency of the Chest Freezer system while making Chest Freezer system a power saving and efficient model.

5.The frost-free Chest Freezer system (100) as claimed in claim 1, wherein, a method is for reversing the valve for operating in heating mode, the method comprising:
if the temperature is lower than the predetermined temperature (T1< predetermined temperature 1) and the time is more than (Time-1>predetermined time 1) the predetermined time, the at least one valve (118) connects to the at least one evaporator coil (104) through the at least one heating pipe (124) to operate in heating mode;
the at least one evaporator coil (104) releases the absorbed heat in the heating mode to melt the frost in the cooling cabin (102);
the at least one evaporator coil (104) releases the absorbed heat till the temperature goes lower than the predetermined temperature and time exceeds the predetermined time (Time-1>predetermined time 2), the at least one valve (118) will get reversed to connect the at least one compressor (108) with the at least one condenser (132) to operate on cooling mode.
6. The frost-free Chest Freezer system (100) as claimed in claim 5, wherein, Time-1>predetermined time 1) is in the range of 24 hours to 72 hours.
7. The frost-free Chest Freezer system (100) as claimed in claim 5, wherein, Time-2>predetermined time 2) is in the range of 10 min to 120 mins.
8. The frost-free Chest Freezer system (100) as claimed in claim 5, wherein, (T1< predetermined temperature 1) is in the range of -10 Degree Celsius to -70 Degree Celsius.
