How does a gas refrigerator work

Condensation forms in the device during operation. The manufacturers took care of this and put a special drain into the hole that goes into the back cover. This allows the unit not to defrost for 2-3 weeks. In addition to the main chamber, there is a freezer.

A heating element is installed inside the unit. It can provide mains power operation. At the bottom, there is a fitting for connecting to a gas cylinder. Heat exchange occurs due to the grate, which is visible from the back.

The unit is powered by a propane tank connected to it. On average, one cylinder is enough for a month of use. Outwardly, such models are similar to ordinary refrigerators. In addition, they maintain the same temperature, equal to +35 °F to +39 °F degrees in the refrigerator compartment and from 5 °F to 23 °F degrees in the freezer.

The essence of cooling is heating a mixture of ammonia and water, which occurs due to the combustion of gas.

The absorption-type model is considered widespread. Ammonia is used as the refrigerant and water is the absorbing material. It works in such a way that the gas heats the water-ammonia mixture to a boil.

The boiling point of ammonia is lower than the boiling point of water. This leads to the process of evaporation of concentrated ammonia vapors, they pass through the heat exchanger, condenser, and evaporator. Coming out of the evaporator, the vapors meet with the absorbent and are cooled. The solution is circulated continuously.

Constructive elements of a gas refrigerator:

  • Generator;
  • Heater;
  • Condenser;
  • Evaporator;
  • Absorber.

Features of the gas refrigerator:

  • The temperature regime does not differ from the electric models;
  • It functions both from a gas cylinder and from the mains;
  • The design does not include shut-off valves and moving parts.

Gas refrigeration chambers are safe, reliable, and durable. Small dimensions of the car refrigerator provide convenience during transportation and save space in the car.

Pros and cons of a gas refrigerator

Pros and cons of a gas refrigerator

  • Able to operate smoothly from different power sources. Includes standard plugs, LPG, and car cigarette lighter plugs.
  • High performanceand energy efficiency.
  • Wide assortmenton the market.
  • Quiet work. The design of the gas refrigeration chamber does not provide for the presence of a compressor or other moving parts. As a result, there are no vibrations during operation.
  • After switching off, the unit maintains temperature for a long time.
  • Durability. The absence of vibrations reduces wear on all equipment and individual parts.
  • Efficiencyis achieved due to operation from gas cylinders. Gas is an environmentally friendly product with low cost.

Gas units are created in different sizes and dimensions. This allows you to select them for different conditions. There are capacious samples. There are also small ones that can easily fit in a car. Compared to standard models, they contain fewer products.

How to choose a gas refrigerator

When choosing a gas refrigerator, follow the same rules as to when choosing a regular one.

Gas units are produced in the form of small models, with a volume of up to 35 liters, and in the form of floor samples, with a volume of 100 liters or more. Large ones include refrigerating and freezing chambers, small ones – only refrigerating chambers.

The price varies depending on the volume. Compared to models that operate only from the mains, gas appliances are an order of magnitude more expensive. Car refrigerators are inexpensive due to their small size.

Consider the climate class – this is a parameter that characterizes the climatic conditions during operation.

There are classes:

  • N – from 60 °F to 90 °F degrees;
  • SN – from 50 °F to 90 °F degrees;
  • ST – from 60 °F to 100 °F degrees;
  • T – from 60 °F to 110 °F degrees.

Additional functions and equipment of the gas refrigerator:

  • Automatic defrosting;
  • Temperature indicator on the panel;
  • Sound and light signals;
  • Alarm;
  • Antibacterial coating;
  • Wheels for transportation;
  • No Frost function – air circulation prevents ice formation;
  • Super cooling mode for fast temperature reduction (Super Cool);
  • Economical modes of operation.

There are mechanical and electronic control types for the refrigerator. With their help, the temperature regime inside the chambers is regulated. The electronic type is equipped with a display that shows information about the operation of the unit.

Car gas refrigerators

In addition to being used at home, a gas refrigerator allows you to make a journey or a long work trip comfortable – we are talking about an automobile version. With its help, food will keep fresh and cool even in the hottest weather. There are many varieties of car refrigerators, but gas appliances are considered to be the most comfortable ones. The noiselessness of the device is determined by the absence of moving parts.

Car gas refrigerators

The battery of the car does not waste energy to maintain its performance, and the compact size and soundlessness allow you to install the device in places intended for recreation – dachas, boarding houses, hotels, sanatoriums.

A car refrigerator cannot operate in a full-fledged mode like the usual household equipment. The moment it reaches extremely low temperatures comes much more slowly. It differs from a conventional refrigerator in its compact size, which allows it to hold a small amount of food.

Despite the fact that many consider this operation not entirely safe, most people want to buy a car refrigerator at a low price.

The equipment fully functions not only in the car, but also in a room that cannot provide a connection to the network, and the used gas cylinders cost much less than their own electric generator. These units can be used in remote places: they are reliable and easy to control, they operate on gas, household power supply, and car cigarette lighter.

How to use the fridge on gas

The devices are equipped with a refrigerator and freezer, internal lighting, and a comfortable temperature regime.

The absorption refrigerator runs on propane. Switching on is carried out with a hose through the reducer to the fitting. You can install the product anywhere. Better to stop on a vertical flat surface. It should be borne in mind that the back wall generates heat and heats up nearby objects.

Gas models generate more heat than conventional models. Therefore, it is better not to place the refrigerator near the wall.

The installation corresponds to the installation scheme of the gas stove. The hose with the reducer is connected to the fitting. To switch from cylinder power to electricity, the refrigerator is connected with a cord to a standard outlet. Remember to disconnect the gas cylinder first.

Electric-powered models are equipped with a gas cut-off system. It works automatically and responds when it detects a problem with the burner flame.

There are LED lights inside the refrigerator for lighting. They run on batteries that can withstand a load of 1 year. If the battery runs out, you can switch to powering the lamps through the network. In this case, the unit itself operates from a cylinder.

There are models that have a temperature control function. It is carried out when working from gas and electricity.

Do not use powders or acids for cleaning. This will scratch the inner surface and rust will form in these places.

Careless loading of food will damage the surface, and chipped enamel can get into the food. During defrosting, do not use sharp objects to remove ice and snow from the evaporator. The gas set must not be covered during operation. Make sure the door closes tightly.

Gas refrigerator precautions

Gas refrigerator precautions:

  • Install the refrigerator in a well-ventilated area;
  • Do not install in humid and dusty places;
  • Do not install near open sources of fire;
  • Protect from direct sunlight and water (rain);
  • Do not place the refrigerator near heat sources, it is better to place it in a cool place;
  • Carefully move the gas cylinder;
  • Use only specialized gas cylinders;
  • Before starting work, check the serviceability of all hoses and other connecting elements, they must be tight and not let gas pass;
  • When connecting the gas stove to the mains, make sure that one power supply unit is connected to one. Do not overload the system to avoid wiring problems;
  • Do not use a cracked or damaged connection cord;
  • Do not store a lot of things on the top cover of the refrigerator;
  • Do not store volatile or flammable substances or liquids inside the refrigerator;
  • Periodically ventilate the room and monitor the ventilation of the air;
  • Do not put water on top of the refrigerator is connected to the mains.

In order for the refrigerating chamber to work for a long time and without interruption, immediately after the purchase, you need to wash the inner doors and shelves with warm soapy water, wipe dry and ventilate. At the beginning of the operation, it is recommended to ventilate the unit at intervals of 2 weeks.

Gas refrigerator malfunctions

Most often, during operation, they are faced with the problem of raising the temperature in the combustion chamber. This happens when connected to a cylinder. Failure of the main mechanisms is eliminated by replacement.

Failure of the shelf and door mountings is possible. Problems with sound and light alarms are eliminated by replacing the defective part.

Popular malfunctions relate to burning the burner – after idle time, the device simply does not turn on. The continuous operation will increase the temperature in the freezer and refrigerator compartment.

Evaporator refrigerant may leak. To neutralize the problem, a full diagnosis is carried out.

The breakdown of the thermostat occurs due to non-stop operation. Ice and snow build up in the freezer if the door is not closed tightly. In this case, the seals on the door are replaced.

Gas equipment is life-threatening, so it is better to entrust the repair to professionals.
