Refrigerator Gas: how it works, the pros how to choose

Such a refrigerator is considered environmentally friendly. It is equipped with one or two cameras. Powered by gas and electricity. This purchase will be useful when staying in a trailer or in a place where there are problems with electricity.

How does the refrigerator on gas

During operation, the condensate formed in the apparatus. This was taken care of manufacturers, and took a special sink in a hole that goes into the back cover. This allows us not to defrost the unit for 2-3 weeks. In addition to the main chamber has a freezer.

Inside the unit is installed heating element. It can can provide work from the mains. At the bottom is a connection for connection to the gas cylinder. Heat transfer takes place due to the lattice, which can be seen from behind.

The unit works on the connected cylinder propane. On average, one bottle is enough for a month of use. Externally, these models are similar to ordinary refrigerators. Furthermore, they maintain the same temperature of from +2 to +4 degrees in the refrigerating compartment and from -15 to -5 degrees in the freezer.

A common model is considered absorption type. The used ammonia as the refrigerant and absorbent material is water. It operates in such a way that the gas heats the water-ammonia mixture to a boil.

ammonia boiling point below water boiling temperature. This process leads to evaporation of concentrated ammonia vapors, they pass heat exchanger, a condenser and an evaporator. Coming out of the evaporator, the pair meet with desiccant and cooled. Circulation of the solution occurs in the continuous mode.

Structural elements:

• Generator;
• Heater;
• Capacitor;
• Evaporator;
• Absorber.

Features:

• The temperature regime is no different from the electric models;
• Functions and from the gas cylinder, and from the power supply;
• The design does not involve the presence of shut-off valves and moving parts.

Gas coolers are safe, reliable and durable. Small size car refrigerator ensure its easy transportation and space saving in the car.

Pros and cons of the refrigerator on gas

• Able to function smoothly from different power sources. It includes a standard socket, liquefied gas and the ability to operate from a car.
• High performance and energy efficiency.
• A wide range of the market.
• Quiet operation. The construction of the gas cooling chamber does not provide for the compressor and other moving elements. As a result, during operation there are no vibrations.
• After turning off the unit for a long time keeps the temperature.
• Durability. Due to the lack of vibration is reduced wear of all equipment and parts.
• economy It is achieved by the operation of the gas cylinders. Gas - an environmentally friendly product at a low cost.

Gas units are of different sizes and dimensions. This allows you to pick them up for different conditions. There roomy samples. There are also small, which can easily fit in a car. In comparison with the standard models, they contain a minimal amount of the products.

How to choose a refrigerator on gas

When choosing a gas cooler refer to the same rules as in the conventional selection.

Gas aggregates are produced in the form of small models of up to 35 liters, and a floor sample volume of 100 liters. Large include refrigerators and freezers, small - only refrigeration.

The price varies depending on the volume. Compared with the models only work from the mains, gas devices are much more expensive. Car refrigerators are inexpensive due to small sizes.

Consider the climate class - a parameter that characterizes the climatic conditions during operation.

Distinguish classes:

• N - from +16 to +32 degrees;
• SN - from 10 to 32 degrees;
• ST - from + 18 to +38 degrees;
• T - from +18 to +43 degrees.

Additional features and accessories:

• Automatic defrosting;
• Temperature indicator on the panel;
• Sound and light signals;
• Alarm;
• Antibacterial coating;
• Wheels for transportation;
• Feature No Frost - air circulation prevents the formation of ice;
• supercooling mode to rapidly reduce the temperature (Super Cool);
• Economical modes.

Distinguish between mechanical and electronic control type refrigerator. With their help regulated temperature conditions within the chambers. E-Type equipped with a display, which displays information about the operation of the unit.

How to use

The devices are equipped with refrigerators and freezers, interior lighting, comfortable temperature.

Absorption refrigerator runs on propane. Turning is performed by means of a hose to the nozzle through a gearbox. Can install the product anywhere. Better to stay on a vertical flat surface. Keep in mind that the back wall generates heat and heats the surrounding objects.

Installation scheme corresponds gas stove installation. Hose with a gear connected to the union. For the transition from cylinder to supply electric power, a refrigerator is attached by a cord to a standard power outlet. Be sure to first disconnect the gas cylinder.

Model with the function of the power from the electric power are equipped with a gas cut-off system. It works automatically and is activated when it detects problems with the burner flame.

Inside the refrigerator, there are LED lamps for light. They are working on batteries that are capable of withstanding the load of 1 year. If the battery runs out, you can go to the food through a network of tubes. At the same time he is working on the unit bottle.

There are models that have a function of temperature regulation. It is carried out during operation of gas and electricity.

Can not be used for cleaning powders or acid. This will scratch the inner surface and in these places then formed rust.

When careless loading products damaged surface and the portion of the cleaved enamel may get into the food. When defrosting not use sharp objects to clean the evaporator of ice and snow. During operation, the gas unit must not be covered. Make sure the door is firmly closed.

Precautionary measures:

• Set cooling chamber in a well ventilated area;
• Do not install in wet or dusty places;
• Do not install near open fire sources;
• Keep away from direct sunlight and water (rain);
• Do not place the refrigerator in the heat of action area, it is better to put in a cool place;
• Gently move the container with gas;
• Use only special gas cylinders;
• Before operation the serviceability of all hoses and other connector elements, they must be sealed and not to pass gas;
• When connecting the gas stove to the power supply, make sure that a single power supply was connected one. Do not overload the system, so no problems with the wiring;
• Do not use the cord to connect, having cracks and damage;
• Do not store a lot of things on top of the refrigerator;
• Do not store volatile and flammable substances, and the liquid inside the refrigerator;
• Ventilate the room and watch for air ventilation;
• Do not place on top of the water, if the refrigerator is plugged in.

Freezer to work long and smoothly, right out of the need to internal doors and shelves washed with warm soapy water, wipe dry and ventilate. At the start of operation it is recommended at intervals of 2 weeks to ventilate the unit.

malfunctions

In most cases when operating face the problem of raising the temperature in the combustion chamber. It occurs when connecting to a cylinder. Failure of the basic mechanisms of eliminating replacement.

Possible failure of anchorages shelves and doors. Problems with acoustic and visual alarms are eliminated by replacing the faulty parts.

Popular fault relate burner burning - after layup unit simply not included. Continuous operation results in an increase in the temperature of the freezing and refrigerating chamber.

The refrigerant may leak from the evaporator. To neutralize the problem of a complete diagnosis.

Teromoregulyatora breakage occurs due to work without interruption. In the freezer there is ice and snow, if the door is not properly closed. In this case, replaced the seals on the door.

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