What is the pipeline system design？

Pipeline system  design refers to the design of the refrigerant compressor and a variety of refrigeration equipment, components connected together to form a reasonable cooling system, including the diameter determined, heat pipes and fittings and pipe layout. Cold storage installation design is good or bad, whether related to the refrigeration unit has good cooling performance, stable and secure operation is also related to the degree of cold storage easy installation process and install the exhaust pipe operation.

Purpose of the pipeline system design

The purpose of cold storage  system piping design is to ensure that all of the evaporator can be adequately for the fluid volume, reasonably determine the diameter of each part of the pipeline, and to shorten the length of the pipeline refrigeration pipes, to avoid excessive pressure loss, so cold mounting system have a good economy, but also to prevent fluid strike and piping systems refrigeration compressor oil in the plot.

Influencing factors of the pipeline system design

The main impact of the pipeline design are two factors: the pressure drop and flow rate of the pipe. Refrigerant pressure drop in the pipeline will reduce the cooling capacity and increased power consumption, lower energy efficiency, and therefore should avoid excessive pressure drop. Usually the pressure drop in the liquid pipe does not directly affect the cooling capacity, but the pressure drop in the liquid pipe must ensure that the liquid is saturated before the liquid enters the throttling device, liquid pipe causes excessive pressure drop in the liquid line generated in flash steam generating capability before throttling flash steam will directly affect the control and regulate the flow of the throttle device, the pressure drop. To reduce the diameter of the liquid pipe pressure drop increases, it will cause the system to inject the refrigerant charge amount. Excess refrigerant will seriously affect the control flow of the refrigerant in the low pressure side of the refrigeration system, a large inertial effect will cause the liquid refrigerant in the refrigerant flow control device movement disorders. In the exhaust pipe and the suction pipe of the evaporator should maintain sufficient flow velocity, because the oil and the refrigerant vapor is not easily mixed, and only the refrigerant flow rate is large enough to carry refrigeration oil moves along the oil circulating in the system to function properly.
