Freezer is the gismo that claim the climatic characteristic below the freezing point of water which operates at 0 F (-18 degree C). Cooling is achieved by evaporating refrigerant (working fluid) or refrigerant media under reduced pressure to lower climatic characteristic of the refrigerant to sop up heat from surroundings. Freezer is utmost necessary in every house because it not only shelters the freezing food but also preserves the fruits, vegetables, milk and other products for longer duration and makes the home maker's work easier by avoiding frequent visits to the markets. Manufacturing associates come up with assorted models, size and intense features to satisfy the consumer's need. You can anticipate the freezer life span to be 8 years, but the life span can be extended with assorted factors. Before accounting for the factors to heighten the life time of freezer you need to know the working of it.
Freezer works based on the vapor-compression cycle. The refrigerant superior (working fluid), which has low boiling point is propelled to compressor where the climatic characteristic and pressure is high and hot too. It then flows to the 1st heat exchanger, the condenser where the heat is detached at high pressure. Refrigerant gradually converts to liquid phase flows to the expansion valve where the pressure is low causing the refrigerant to flash into liquid & vapor blend with low temperature. Then the flow is to the 2nd heat exchanger, the evaporator where the refrigerant sucks up heat production the refrigerant to vapor phase.

Then the flow is to compressor again and the cycle reiterates. This methodology is precious and not vigor sufficient too. To avoid this drawback, charging element chose to offer triboelectric charge over refrigerant thereby disrupting the intermolecular military by breaking of covalent bonds and van der waals military prominent to expansion and transition of liquid to vapor phase. Then ultimately the rate of nucleation increases with decreased bubble generation and enhanced vigor efficiency. You can feel the voltage generated by triboelectric charge to be higher than 70Kv.
Triboelectric charge is obtained when 2 distinct electrostatic materials come in contact. So the charging element is superior from the ultimate end of the series containing the list of lower to higher work function materials to report higher charge to the refrigerant. For example low work function materials -dry human hair, asbestos, leather, rabbit fur, acetate, glass etc. High work function materials- silicon rubber, Teflon, silicon, Pvc, polypropylene, etc. The carrying out is enhanced when climatic characteristic of working fluid is 20 degree C - 90 degree C at condenser and -85 degree C- 25 degree C at evaporator.
Working fluid may be ammonia, methane, ethane, propane, pentane, carbon-di-oxide etc. Most favorite may be multi-component Hfc mixture, tertiary refrigerant mixture. Ordinarily the triboelectric element is positioned between condenser and evaporator. The electrostatic charge increases heat replacement rate, heat flux, thermal capacity of heat exchanger thereby decreasing compressor power, fuel consumption. Sometimes more than one triboelectric union is placed in freezer to heighten the coefficient of performance, thermal capacity etc. Magnetic field is also employed to growth vigor efficiency, performance.
Frost build up may sway the freezer which is introduced because of humidity it acquires when the door opens. Auto defrost units with blower fan to keep the moisture aside of the unit and heating coil below evaporator that warms the freezer thereby melting ice-crystals are featured in recent freezer. Condenser is the most necessary part in inspecting the life span of freezer. It fails due to overheating because of insufficient air flow. Cleaning of condenser coil and removing the dirt placed over the fan blades is necessary. Freezer with clean condenser discharges more heat without causing strain to mechanical parts by drawing less current. These factors without fail lead to the increased life span of freezer.
