Title: System for heating with hot water
Inventor: FUJIMOTO MOTOAKI
IPC: F24H6/00
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To enable full display of the capacity of a fan convector in a system for heating with hot water which has floor heating equipment and the fan convector. SOLUTION: In a system for heating with hot water wherein hot water from a heat source machine 20 can be circulated through floor heating equipment 2 and a fan convector 6 and the temperature of the hot water from the heat source machine 20 is made variable, input parts 21 and 22 of boiler control equipment 23 of the heat source machine 20 receive as inputs ON-OFF signals of operation from the floor heating equipment 2 and the fan convector 6 at least. A hot water temperature determining part 25 judges whether they are operated or not, from the inputted ON-OFF signals of operation, and when the fan convector 6 alone is operated, it neglects a set temperature of hot water of the floor heating equipment 2 and determines a temperature (a fixed value of 80 deg.C) matched with the fan convector 6.  At the time when the floor heating equipment 2 alone is operated, it determines the set temperature set by a hot water temperature setting part 23 and sent by a signal from the floor heating equipment 2 or the previous set temperature as a hot water temperature at this time.

Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To improve the utilizing efficiency of frequencies while suppressing the increase in the hardware and to realize accurate demodulation processing by instructing generation of a spread spectrum code based on correlation detection result. SOLUTION: An instruction means 12 instructs consecutive generation of a current spread spectrum code to a generating means 10 when a detection means 11 detects coincident correlation and instructs generation of a spread spectrum code of other period pattern to the generating means 10 when a detection means 11 detects dissident correlation. An inverse spread means 13 applies inverse spread processing to a received signal by using a spread spectrum code whose timewise direction is inverted to that generated from the generating means 10. Through the adoption of the configuration of searching a spread spectrum code used for generating the received signal to receive the reception signal, the reception signal generated by using the spread spectrum code of a different period pattern is attained and the frequency utilization efficiency is improved.
