RADIATION AIR-CONDITIONING SYSTEM
Document Type and Number:
Japanese Patent JP2018141566
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a radiation air-conditioning system capable of executing stable and responsive control without costs.SOLUTION: A radiation air-conditioning system for adjusting a temperature of an air-conditioning objective space by circulating cold and warm water through a radiation panel provided in the air-conditioning objective space has: a room temperature sensor for measuring the temperature of the air-conditioning objective space; an inlet side temperature sensor of the cold and warm water circulated through the radiation panel; an outlet side temperature sensor; a flow rate sensor for measuring a flow rate of the cold and warm water; load prediction means (step S102) for predicting a load from the temperature of the air-conditioning objective space, an inlet side temperature and an outlet side temperature of the cold and warm water, the flow rate of the cold and warm water and a heat balance model in the air-conditioning objective space; target temperature setting means for setting a target room air temperature; a flow rate controller for controlling the flow rate of the cold and warm water; and a main controller (step S105) for determining a command value to the flow rate controller from the predicted load, the target room air temperature and the inlet side temperature of the cold and warm water.SELECTED DRAWING: Figure 5
