Title:
HOT-WATER TYPE FLOOR HEATING SYSTEM
Document Type and Number:
Japanese Patent JP3806256
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To control warm water in 2 systems of heating floor with one room temperature sensor.
SOLUTION: The present floor heating system supplies hot water at a predetermined temperature from a single heat source machine 1 to 2 system heating floors 2A, 2B, and on-off duty of control valves 3A, 3B interposed between pipings of each system for temperature control. In this case, one of the 2 systems is assumed to be a priority system with the other a subsystem. The control valve 3a on the priority side controls temperature with the aid of a predetermined correlation function or a correlation table such that a difference between an output of the room temperature sensor and set room temperature is more reduced. The slave system side control valve 3B provides a bias approximately to a temperature difference of the correlation table in response to the difference between the priority system and the set temperature. Hereby, temperature can be controlled with the same correlation function and the correlation table.
