Abstract

The utility model relates to an energy saving device for household refrigerator, which is composed of an upper water box, a lower water jacket tank body which contacts surfaces of a condenser and a compressor, a rising pipe and a down pipe. The upper water box is arranged above the condenser of the household refrigerator, the upper water box and the lower water jacket tank body are communicated to form a natural circulation cycle through the rising pipe and the down pipe.

Description

Energy saving device for household refrigerator

The utility model relates to a kind of energy saver, especially for the energy saver on the refrigerators such as domestic refrigerator, air-conditioning.At present, refrigerator, refrigerator-freezer, air-conditioner (Dan Leng is away from formula) have become people's indispensable electric equipment of living, the operation principle of these refrigerators mainly is to lean on the cold-producing medium of low boiling temperature to produce high-temperature high-pressure overheat steam by compressor, cool off through condenser air, again through the capillary expansion valve to evaporimeter with heat absorption, constantly circulation is freezed.Therefore, environment temperature is high more, and its heat radiation is long more the duration of runs, and power consumption increases.And the heat that is distributed during the work of these family expenses refrigerators also can cause the rising (as refrigerator) of subenvironment temperature.In addition, the air Natural Circulation or the forced circulation thermal resistance of condenser are big, and heat transfer efficiency is low, and the heat that it distributes is wasted.

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of and can improve family expenses refrigerator radiating effect, reduces energy resource consumption, improves the family expenses refrigerator energy saver of subenvironment temperature.

Technical solution of the present utility model:

A kind of family expenses refrigerator energy saver, it is characterized in that it is by upper tank (1), bottom water jacket casing (2) and tedge (3) and down-comer (4) are formed, upper tank (1) is arranged on the top of the condenser (5) of family expenses refrigerator, bottom water jacket casing (2) is a closed cavity, its top contacts with the surface of condenser (5), its bottom wraps the compressor (6) of family expenses refrigerator, upper tank (1) bottom is communicated with the bottom of bottom water jacket casing (2) by down-comer (4), the top of bottom water jacket casing (2) is communicated with upper tank (1) by tedge (3), forms natural convection loop.

The utility model adopts Natural Circulation water as cooling medium, replaces the air dielectric that thermal resistance is big, heat transfer efficiency is low, and the air heat transfer coefficient of free convection is 5.8-8.2W/m ²K, and the heat transfer water coefficient under the free convection is 400W/m ²K has effectively improved the radiating effect of unit are.The utility model has also improved the radiating efficiency of condenser, has shortened the available machine time of compressor, thereby has saved power consumption and improved the electrical network pressure of city electricity consumption peak point in summer.Available machine time owing to compressor shortens simultaneously, so slowed down the thermic load of compressor and the insulation effect of the interior long-time running of assurance machine, the service life that can prolong compressor.Also can reduce by a condenser fan for the single-cooling type air-conditioning.The utility model can change the subenvironment temperature (the high-temperature high-pressure overheat steam temperature is between 70-80 ℃, and the temperature of compressor is 100-115 ℃) of refrigerator with the water tank accumulation of heat, but its cooling water vibration and noise that also absorptive condenser, compressor produced.The hot water of the utility model savings can be used to the usefulness for family's bathing summer, the consumption of having saved other fuel, comprehensive obvious social benefit.

Fig. 1 is a structural representation of the present utility model.

As Fig. 1, during the utility model work, earlier upper tank (1) is added water to normal water level from water inlet pipe (7), family expenses refrigerator structures such as its refrigerator, refrigerator air conditioner are constant, condenser (5) still is connected with evaporimeter, and the communicating pipe route (8) of compressor is constant.When the family expenses refrigerator is worked, because bottom water jacket casing (2) outer wall contacts with the surface of condenser (5) with compressor (6), also the both side surface of condenser (5) can be wrapped, then temperature is that condenser radiating tube about 70 ℃ and compressor outer wall are absorbed heat by conduction by the water in the bottom water jacket casing (2), and after water was heated, hot water proportion changed, molecule produces motion, hot water rises naturally, and cold water descends naturally, produces Natural Circulation.Enter hot water and its inner cold water natural layering of upper tank (1), hot water is last, and cold water is following, and start hot water is up, and cold water is descending, shuts down to keep balance, thereby reaches the radiating efficiency that improves the family expenses refrigerator, purposes such as saving power consumption.The hot water of being saved can reach about 60 ℃, after stirring, can pass through outlet pipe (9) and insert the bathroom use.

Claims
