Refrigerate Condenser Coils

Optical Refrigerator Defrost Controller reduces energy usage.

August 25, 2011 - To conserve energy, Ice*Meister(TM) Model 9734-REFR minimizes frost accumulation on evaporator coils and fins of commercial walk-in refrigerators, reach-in refrigerated display cases, and other self-defrosting chiller systems. Product works by sensing interaction between molecules of accumulating frost and photons of light and then operating defrost heaters only when frost is present. Control can be installed on any refrigerator at factory or retrofitted in field. Fort Lauderdale FL -- New Avionics Corporation here announces a new optical defrost controller for commercial walk-in refrigerators and reach-in refrigerated display cases, and other self-defrosting chiller systems in supermarkets, restaurants, school cafeterias, convenience stores, and refrigerated display cases for sushi, pastries, gelato, ice cream, and other delicious foods. FROST is a major concern in the food-service industries because frost is a thermal insulator that forms out of thin air, and accumulates on refrigerator coils and fins. Frost interferes with proper heat transfer. Every time a refrigerator door is opened and closed, outside air enters. The outside-air humidity can be higher than that of the refrigerated air inside, and so dew can appear and freeze on the refrigerator's internal components. The problem is that defrost cycle control is normally under control of primitive electro-mechanical timer clocks. There may be little or no relationship between the application of defrost heater energy and the frost which it is supposed to eliminate. This causes a wasteful disparity between refrigerator defrost cycles and the function they are intended to accomplish. By replacing primitive defrost timers, new Ice*Meister(TM) optical de-frost heater control helps reduce, limit and prevent all insulating frost. NASA-tested Ice*Meister(TM) works by sensing the interaction between molecules of accumulating frost and photons of light. It conserves energy by operating defrost heaters when and only when frost is present, whereas primitive timers can be hit-or-miss. The quantified amount of energy to be saved depends on a number of local variables, including time of the day, ambient humidity, temperature, season of the year, staff diligence, local customs, etc. In operation, Ice*Meister(TM) senses the very earliest appearance of frost on refrigerator coils (see figures B & C). As soon as frost appears, Ice*Meister(TM) signals the compressor to turn OFF, and the heater to turn ON. This signal immediately begins to melt away offending frost. As soon as the offending frost has been melted away and removed, Ice*Meister(TM) signals the heater to turn OFF and turns the compressor to turn back ON again. The refrigerator then returns to normal operation, with its defrost controller sweeping back-and-forth across the frost-formation threshold, and actively keeping the condenser coils frost-free. Ice*Meister(TM) can be installed on any refrigerator at the factory, or retrofitted in the field as an aftermarket product. It eliminates all moving parts, reduces parts count, reduces cost to manufacture, improves reliability, and saves Megawatts of electricity, worldwide. Ice*Meister(TM) controls any refrigerator's defrosting system to sweep back and forth across the ice formation threshold in real time.

Refrigerator Frost Problems

Keep refrigerator frost free

Like an air conditioner, refrigerators operate on a standard cycle. A compressor pushes refrigerant through 2 connected sets of coils. In the low pressure area of the evaporator coils inside the unit, the refrigerant becomes a gas and absorbs heat. The high pressure condenser coils on the outside while the gas becomes liquid and loses heat to the room air.

One other important element with regards to this area of interest. Frost buildup is a large obstacle to efficient refrigerator operation. Most systems use either an automatic frost free or a semiautomatic cycle defrosts method to melt the frost. On frost free modules, a timer turns on a defrost heater about 2 times a day to warm up the evaporator coils. The evaporator coils are encased in the back or floor of the freezer . A fan is also encased that helps circulate air over the coils and into the food compartment. A cycle defrost system keeps only the refrigerator frost free; keeping the freezer defrosted is a manually process. On both types of defrost systems, the melted frost drains down into a pan that sits under the unit and evaporates.

How to tell whats wrong with my refrigerator? My refrigerator has gone out and I'm trying to figure out if it's something simple like it needs freon added to it or something or if I'm going to have to buy a whole new fridge. At first i noticed my milk was going bad very quickly so I thought something was wrong with it but now a few weeks later the ice cubes in my ice cube tray have stopped freezing so now both the refrigerator and freezer aren’t staying cold enough. I’ve even tried to turn my refrigerator settings all the way down and still haven't had any success with that. Can someone give me some suggestions or options on what I can do to get it fixed the cheapest way possible or if I’ll have to buy a new fridge? Its a kenmore brand fridge if that helps.
