Receiver simple tank, as the device is used for storage of liquid refrigerant inside the mechanical refrigeration system. This storage is needed on some systems for the following purposes:
Adapting to changes in the process of exploitation.
Freely drain condenser refrigerant.
The use of refrigerant floodback method of head pressure.
Provide a place to store system boards within the system and procedures of the service or extended periods of inactivity.
Receivers is not required for some refrigeration cycles and should not be set if required. The receiver is in the liquid line between the condenser and the metering device. Usually it is very close, and below the condenser.
All systems using the manual expansion valve, automatic expansion valve, thermostatic expansion valve or the low side of the float valve as liquid metering device require some means of storage of refrigerant in the process of exploitation.
Operating the refrigerant in the evaporator change significantly when the load changes. It decreases as the cooling load increases, as the boiling point of more intense. In addition, it increases the load decreases. Refrigerant pushed out of the evaporator in a larger cooling loads must be stored somewhere. Residential and commercial systems comfort often store the excess in the condenser. In such cases, the capacitor several oversized hold further, in supercooled liquids providing sufficient performance at peak load. When this is done, the receiver is not needed. On other systems, but a complete surface of the condenser is necessary to condensation receiver is used to store surplus refrigerant.
There are different types of receivers. This is one of flow type. In a flow-type, all the liquid flows through the receiver before you move to the metering device. Liquid, leaving the receiver will be saturated, as both liquid and vapor are present in it.
Splash-type of the receiver accepts the positive balance in the refrigerant and produces what you need. Thus it allows the supercooled refrigerant from the condenser to transfer metering device. Thus, hypothermia can still be provided through the condenser, without getting lost in the receiver, as in the flow type.
Advantages of placing the receiver in a system are that it:
Allows for maximum capacity to be reached from the condenser.
Provides refrigerant storage area, beside the main components for system maintenance. It is also useful for long periods of downtime.
Permits a wider variation of the refrigerant in the authorized operating charge, which greatly simplifies maintenance.
Allows the refrigerant floodback methods pressure control can be used if necessary.
Disadvantages receiver that he:
Adds the cost of the receiver and its fittings and pipelines, as well as for the system.
Complicates the design of the pipeline. This increases the cost of design and installation.
Makes hypothermia difficult to achieve when using the flow-through design.
