Title:
TEMPERATURE CONTROL DEVICE AND TEMPERATURE REGULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/261749
Kind Code:
A1
Abstract:
Provided is a temperature control device capable of more suitably controlling temperature even when the number of temperature regulation target sites is increased.　The temperature control device is for controlling temperatures in temperature regulation target sites of a temperature regulation target device in a temperature regulation device comprising a refrigerant circuit. A communication module of the temperature control device is configured so that target temperature information for each temperature regulation target site contained in a communication frame periodically received via a field network is stored in a prescribed location in memory. A calculation module of the temperature control device receives the target temperature information for each temperature regulation target site, receives refrigerant temperature information indicating the current temperature of a second refrigerant from each temperature sensor corresponding to each temperature regulation target site, and calculates, on the basis of the received target temperature information and refrigerant temperature information, control parameters for adjusting the degree that each corresponding control valve is open so that each temperature regulation target site reaches the target temperature indicated by the received target temperature information.
