Ори вентили за регулацију притиска
ORI pressure regulator gets its name from its function of design. ORI valve Opens a port on the Growth of the Inlet pressure. The entrance ORI distributors die liquid line from the кондензатор outlet. Thus, control of pressure in the condenser. Its structure is similar to the EPR valve. Both devices respond to changes in pressure at the inlet and die consequences of their oudet no pressure on the valve design. When the temperature of the air around the condenser changes, ARI is modulated in response to fluctuations associated die pressure of condensation. Increase condensing pressure moves tne valve in direction open, while the decline of the condensing pressure forces the valve for modulation in direction close direction.
In periods of low temperature or light loads, the condensing pressure decreases. As approaches to die points ORI valve, she begins to decrease in the flow of liquid refrigerant leaving the condenser. This action causes the liquid refrigerant in the condenser, reducing the number of active heat transfer surface.
Die effective surface area is reduced, the pressure in the condenser begins to grow. ORI valve corresponds to die increase condensing pressure through modulation open to maintain the pressure at the condenser widiin normal operating range. ORI valve to 100% open when condenser pressure within the operating range, and if the pressure is higher than normal, as in periods of high demand...
