A Continuous Cycle Of Absorption System

The block consists of four main partsboiler, condenser, evaporator, and absorber. Cm. Fig. 3-20. When the device uses kerosene or gas, heat, supplied to burners. This element has under the Central tube (A). When working on the electricity heating element is inserted in your pocket (B).

The unit charge consists of a quantity of ammonia, water and hydrogen. These are at a sufficient ammonia condensing pressure at room temperature. When heat is supplied to the boiler system, bubbles of ammonia gas. They rise and spend time with them quantities weak solution of ammonia through the siphon pump (C). This weak in the ammonia solution passes the tube (D), while ammonia vapor passes into the vapor pipe (E) and water separator. Here any water vapor condenses and runs back into the system, leaving the dry vapor ammonia to the condenser.

Circulates the air over the condenser plates removes heat from ammonia vapors. It condenses to a liquid ammonia and then enters the evaporator. Evaporator comes with hydrogen. Hydrogen is on the surface of ammonia. He lowers the pressure of ammonia vapours enough to allow ammonia evaporates. The evaporation of ammonia extracts the heat from the evaporator. This, in turn, extracts the heat from the space to store food, lowering the temperature inside the refrigerator.

A mixture of ammonia, hydrogen, vapour passes from the evaporator to the absorber. A continuous stream of weak ammonia solution comes in the upper part of the absorber. It is supplied by gravity from the pipe (D). This weak in the ammonia solution flows through the absorber. It comes in contact with mixed ammonia and hydrogen gases. It easily absorbs from a mixture of ammonia. Hydrogen is free to rise through the spring shock-absorber and is returned to the evaporator. Hydrogen continuously circulates between the absorber and the evaporator. A strong solution of ammonia produced in absorber flows absorber vessel. It enters the boiler system that completes the full cycle of operation. This cycle runs continuously until the boiler is heated. Thermostat that controls the heat source, regulates the temperature of the refrigerated space.

With the refrigerant ammonia, it can lead to very low temperatures. Most systems require electrical appliances, as gas and electricity must be provided. In addition to the thermostatic control and {in some cases, fans, no moving parts. Service is usually quite simple. The burner and the stack must be kept clean. The refrigerator should be carefully aligned before being placed in exploitation...
