Title:
CONTROL SYSTEM OF REGENERATIVE AIR CONDITIONING INSTALLATION, CONTROLLED PLANNING APPARATUS, CONTROLLED PLANNING METHOD, AND RECORDING MEDIUM AND PROGRAM FOR EXECUTING THE CONTROLLED PLANNING
Document Type and Number:
Japanese Patent JP2002364901
Kind Code:
A
Abstract:

To provide a controlled method for making a plan wherein the rate of the consumption of electric power and the running cost both of the entire regenerative air conditioning equipment, by calculating the rate of the consumption of electric power and the cost of each of a heat source machine, a load side instrument and a conveying instrument in the regenerative air conditioning equipment.

For dealing with a predicted value of a heat load, after stored heat energy in a heat storage tank in a regenerative air conditioning equipment is detected, a first variable is estimated which minimizes the rate of the consumption of electric power of the whole of the regenerative air conditioning equipment under the conditions of operation of a heat source instrument. Then a second variable is estimated which minimizes the rate of the consumption of electric power of the whole of the regenerative air conditioning equipment under the conditions of the operation of a load side instrument. Further, a third variable is estimated which minimizes the rate of the consumption of the operation of electric power of the whole of the regenerative air conditioning equipment under the conditions of the operation of another instrument. By repeating the cycle of the calculations of those first, second, and third variables a controlled plan is calculated for minimizing the rate of the consumption of electric power of the whole of the regenerative air conditioning equipment and the running cost.
