Before people the question of that how many watts are consumed by the fridge as they didn't think of economy didn't concern. It is connected with the fact that there was no big variety of devices. And electricity cost little relatively. The family budget wasn't left by many funds for utilities. Interested nobody about 30 years ago how many watts are spent, but now this question are considered one of relevant.
The modern dwelling of the person is simply stuffed with various devices without which it is difficult to present everyday ordinary life now. All these devices consume a lot of electric power. Because of big dimensions of the device the first suspicion about what household appliances take away a lot of money of the family budget, falls on the fridge. Modern devices of this kind perform a set of functions. Without them the kitchen won't be oneself. How many watts are consumed by the classical simple fridge, it is necessary to know to everyone. This original indicator in many respects depends on equipment service conditions. How to make so that to reduce consumption of watts of energy of the fridge in day, it will be considered further.
Statistics
Statistically, on households 29% of volume of the electric power of the country are required. This indicator is higher only in the industrial sphere - 31%. The fridge works always therefore it is among large consumers. The German sociologists carried out work on energy use calculation as devices. It was found out that if houses are regularly used home household devices - the washing machine, the vacuum cleaner, the iron, the fridge, then on it 30% of resources leave. By this criterion of the technician is in 1 place. Even for other needs less means, than are spent for operation of devices.
Quality of the fridge
Buying the new equipment, it is necessary to pay attention to recommendations. Feel advantage over time. Cheap devices usually demand additional resources for service. Such equipment for a short time has a wear of sealant on doors, and energy consumption will be considerable. How many will leave electricity for operation of such equipment, even professionals can't tell. Therefore it isn't necessary to save on quality. Having chosen the fridge with suitable consumption, it is possible to save successfully means in what and there is a purchase value. At the same time it won't interfere with comfortable use.
Energy efficiency of the fridge
On modern fridges the interesting marking with the indication of a class of energy consumption is without fail put. This piece - marking actually very serious. Classes only seven: A, B, C, D, E, F, G, however fridges of the classes D, E, F, G aren't issued now – they outdated and not so economic.
To each class there corresponds a certain index of energy efficiency.
What is meant by these figures? If to take the certain mean of the energy consumed by the fridge (counted by practical consideration), then the index of energy efficiency specifies what share from this mean is consumed by the concrete refrigerator.
For example, the class of energy consumption of fridge A corresponds to index 42-55. Means, the fridge of class A consumes no more than 42-55% of average value of the consumed energy. Usually producers place a sticker where the energy consumption class is specified actually on the fridge. It is better to be guided by these figures.
Power
Basic rule such: the device is more powerful and the longer it works, the more electric power consumes. On a sticker from a reverse side of the device it is necessary to look for also information on the power consumption of the concrete fridge. In the operation manual the hypothetical consumption in habitual to us кВт⋅ч is specified. The producer can specify the range of power consumption, and can designate only a maximum. It isn't obligatory to be guided by a maximum: real operation of the equipment usually doesn't demand such victims. Power of modern fridges is from 0.2 to 0.5 kW an hour. For comparison the power of the washing machine - from 1.5 to 2.5 kW an hour.
Operating time
The fridge electric motor in standard conditions works cyclically, i.e. through certain periods joins and switched-off. The relation of a part of a cycle throughout which the electric motor works to the general duration of a cycle is called coefficient of working hours, than it is more the lower temperature in the fridge and the more hourly average expense of the electric power. A certain recurrence in operation of the fridge (coefficient of working hours) is provided by a temperature regulator – the device by means of which temperature in a fridge case is regulated. Are blown loaded into the fridge work as the cold accumulator, the loaded fridge, in comparison with empty, costs to disconnected longer. The coefficient of working hours averages 0.5, i.e. the fridge a half of time is switched off, a half works.
Period of operation of the compressor of the fridge about 50%. Therefore, per day works 0.5*24=12chasov. Naturally, it approximately.
How to calculate energy consumption of the fridge
Now, when operating time and power are known, we have a light way to calculate energy consumption of the fridge per day. The cunning is in quickly to calculate energy consumption of the fridge per day, it is necessary its power consumption (in kW) to increase by time of its work. From the aforesaid it is clear that the fridge works approximately till the 12th hour a day, that its energy consumption will be per day the clear rate received on this formula.
0.2 kW x 12 h = 2.4 кВт⋅ч.
To calculate expenses on the electric power, increase the received number by cost 1 кВт⋅ч on a tariff of your region.
Councils
- Install the fridge far away from batteries and heating devices.
- Don't put a hot product in the fridge. At first cool it to room temperature.
