[0001] The present disclosure relates to refrigeration appliance condensers. More particularly, the present disclosure relates to a device accommodated with concealed static freezing solution.

BACKGROUND

[0002] Generally, the condenser of the refrigeration appliance is used to reject the heat into the surroundings by forcing air, water or any fluid over the condenser thereby extracting heat from the compressed vapor refrigerant which is flowing through the condenser when the refrigeration system is working. In a plug-in type refrigeration appliance such as domestic or commercial refrigeration appliance the heat is extracted continuously from the condenser and released into the surrounding air by way of natural convection or forced convection using electrical fans/blowers etc.

[0003] Most of the existing condensers are exchanging the heat with the surrounding air. The density of air is very low in comparison to most liquids and its heat absorption capacity too is much lower than any other liquid. This makes the condenser length go up many times more than the length that would have been required if liquid was used to absorb the vapor refrigerants heat by flowing over the condenser through which the heated refrigerant is flowing through. The longer length of a conventional air cooled condenser causes pressure drop in the refrigeration system. This pressure drop decreases the efficiency of the refrigeration system. However most of the existing refrigeration appliances are incapable of bringing down the compressed refrigerants temperature down to the ambient temperature as there are practical constraints on size, length, weight and cost of the refrigeration system. This is also a cause of lower energy efficiency of the appliances.

[0004] The static air condensers and the skin condensers inevitably heat one or more sides of the appliance in order to reject the heat. This heated side in-turn causes higher heat gain to the temperature maintained in the refrigerated chamber and causes the compressor to run for longer periods of time to compensate for the additional heat gain. This reduces compressor life and increases the power consumption of the appliance. These static air condenser or concealed skin condensers sometimes get very hot and may cause irritation or can potentially cause burns and remain a cause of safety concern for all people who can come in physical contact with the surfaces these condensers might be exchanging heat from.
The static air condensers that are mostly fixed to the back of the refrigeration appliance are visible and are mostly black in color, which is aesthetically displeasing and are prone to dust settling on static air condensers also by virtue of design they protrude out of the appliance and are highly prone to damage in transportation, in movement from place to place.

[0005] In the light of aforementioned discussion there exists a need of a device accommodated with concealed static freezing solution. That melts at the higher condensing temperature there by absorbing heat to be released later in to the surrounding by freezing at room temperature during the compressor off cycle.

BRIEF DESCRIPTION OF DRAWINGS

[0020] Other objects and advantages of the present invention will become apparent to those skilled in the art upon reading the following detailed description of the preferred embodiments, in conjunction with the accompanying drawings, wherein like reference numerals have been used to designate like elements, and wherein:

[0021] FIG.1 is a diagram depicting a device with concealed static freezing solution.

[0022] FIG.2 is a diagram depicting an exemplary arrangement of a refrigerant condenser coil in a freezing solution for providing condensed refrigerant at room temperature.

DETAILED DESCRIPTION

[0023] It is to be understood that the present disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The present disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

[0024] The use of "including", "comprising" or "having" and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. The terms "a" and "an" herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item. Further, the use of terms "first", "second", and "third", and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

[0025] Figure 1 is a diagram 100 illustrating a device with concealed static freezing solution. According to a non limiting exemplary embodiment of the present disclosure, the device 100 includes an outer condenser tube 102 is filled with a freezing solution 104 in an accommodated hollow space. The freezing solution 104 is in a form of solid state at normal conditions and is used for providing condensed refrigerant at a room temperature. An inner refrigerant condenser tube 106 is designed to pass through the freezing solution 104, which is placed between102 and 106.

[0026] As shown in the Figure 1, the inner refrigerant condenser tube 106 is used to receive a hot discharge gas during an operating mode of freezer through a pipe arrangement 108 for providing condensed refrigerant at the room temperature. The arrangement of the outer condenser tube 102 is placed at a convenient place in the refrigeration appliance; it may include right side, left side, rear side of the freezer and the like. The outer condenser tube 102 is affixed to a base plate 110 of the freezer to dissipate the heat into the surrounding air during the on cycle of the refrigeration appliance. When the freezer is in a state of cut off, the device dissipates the collected and stored heat into the surrounding air. This ensures that none of the heat is being diverted to the external surfaces of the freezer and eliminates any unnecessary heat gain thereby reducing the compressor run time and increasing the refrigeration system efficiency.

[0027] Further shown in Figure 1, the device 100 is used as a condenser of the freezer and it is concealed with the freezing solution 104. For instance, the freezer is in an on cycle during a cooling cycle the hot discharge gas enters the inner refrigerant condenser tube 106 through the pipe arrangement 108 and starts rejecting heat into the freezing solution 104 for providing condensed refrigerant at the room temperature at the exit of the outer condenser tube 102. For handling higher heat loads, the proposed outer condenser tube 102 is used along with a static condenser or an air cooled condenser . The freezing solution helps in absorbing almost all heat from the refrigerant in a very short distance of refrigerant travel. This reduces the refrigerant pressure drop in the system.

[0028] FIG. 2 is a diagram illustrating an exemplary arrangement of a refrigerant condenser coil in a freezing solution for providing condensed refrigerant at room temperature. According to a non limiting exemplary embodiment of the present disclosure, the arrangement includes a condenser tube 202 which is filled with a freezing solution 204 in an accommodated hollow space. For convenience, the arrangement 200 is disclosing only about the freezing solution 204. However it should be understood that in practice there may be a solution as similar as the freezing solution 204 that can be included in the arrangement 200. Therefore, the present disclosed the solution that may be included and/or supported by an arrangement 200 consistent with the disclosed embodiments. The solution 204 is in a form of solid state at normal conditions and is used for providing condensed refrigerant at a room temperature. A refrigerant condenser coil 206 is designed to pass through the eutectic solution 204, in consequence the refrigerant condenser coil 206 is placed in the accommodated hollow space of the condenser tube 202.

[0029] As shown in Figure 2, the refrigerant condenser coil 206 is used to receive a hot discharge gas during an operating mode of freezer through a pipe arrangement 208 for providing condensed refrigerant at the room temperature. The condenser tube 202 is affixed to a base plate 210 of the freezer to dissipate the heat into the surrounding air during a cooling cycle of the freezer. The condenser 202 is concealed in a compressor compartment of the freezer hence is not visible nor is prone to any transit damage as is common with externally protruding, visible, black condensers. For this arrangement the condenser requires no external fans for condensing the refrigerant thereby eliminating a moving part that will eventually fail. By this elimination of the fan the refrigeration system reliability is increased and also a point of power consumption is eliminated thereby increasing the efficiency of the freezer.

[0030] While specific embodiments of the disclosure have been shown and described in detail to illustrate the inventive principles, it will be understood that the disclosure may be embodied otherwise without departing from such principles.
