Now many air-conditioning water system pumps in parallel, chillers in parallel, and then series (GB Atlas is the case), that if the unit and the pump "size with", then how to ensure
After large and small units of their respective constant flow? Use constant flow control valve line? Whether the use of pumps and their respective units in parallel and then the first series in parallel? Of course set the flow valve also
Installed, but this ensures that the large and small units of the respective flow.
This is called chillers, cold water circulation pumps, cooling towers and cooling circulating water pumps in parallel. Cold, circulating pump size with the practice, I have been not agree, but also never
this way. Benevolent see benevolence see wisdom, each have their own good, but good design can always use a relatively simple system configuration to meet the basic use of functional requirements. Cooling towers and cooling water circulation pumps
Also with the size of it? Should be based on the system may be the lowest load, so that a single cold load rate of not less than 30% on it. COP (including boilers) the highest point, and
Non-full load stage.
Two-stage pump system chillers and cold water circulation pump is generally one-to-one matching. While the single-stage pump system should be based on supply and return pressure differential pressure to adjust the opening of the bypass valve, when
When the differential pressure bypass valve flow is more than the flow rate of a circulating water pump (generally need to get from the supply and return water temperature difference), reduce a running water pump, when the differential pressure bypass valve without flow, but real-
Operating pressure is still lower than the set value, the increase in a running pump, not with the actual operation of the number of chillers related.
The above content is based on the actual work of the students encountered problems from the order, for reference, if any problems, timely communication, correction.
