OPERATION COST SAVING VARIABLE FLOW SYSTEM OF COOLING WATER USING AIR CONDITIONING TERMINAL AND COMPOUND VALVE

摘要

Provided is an operation cost saving variable flow system of cooling water using an air conditioning terminal and a compound valve, comprising: a valve disposed at each of a plurality of zones having a cooling load and which variably controls a quantity of flow passing by; a variable speed pump which supplies cooling water to each valve and discharges a variable flow; an inverter which adjusts a number of revolution of the variable speed pump; and a controller which detects changes in the cooling load and thus calculates a total required quantity of flow of the cooling water and then calculates the number of revolution, thereby controlling the inverter.;COPYRIGHT KIPO 2016
