Title:
HEAT SOURCE SYSTEM SETTING TEMPERATURE CONTROL DEVICE, HEAT SOURCE SYSTEM WITH CONTROL DEVICE AND HEAT SOURCE SYSTEM SETTING TEMPERATURE CONTROL METHOD
Document Type and Number:
Japanese Patent JP2017172857
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent a stopping under a light load as much as possible without forcing any excessive operation.SOLUTION: This invention relates to an upper level control device 20 for a heat source system comprising an evaporator for evaporating refrigerant and heat exchanging between the refrigerant and heat source medium; a compressor for compressing the refrigerant; and a condenser for condensing the compressed refrigerant by heat medium, and there is provided a heat source machine for heating the heat medium by the condenser to a prescribed outlet set temperature and supply it to an external load. There are provided a load calculation part 23 for calculating a difference between a first load factor of the heat source machine during its operation and a second load factor in which the heat source machine becomes a minimum heating power transferring to a light load stopping; and a set temperature changing part 24 for decreasing the outlet set temperature of the heat source machine at the first prescribed rate lower than the initial value when the difference calculated by the load calculation part 23 becomes less than the first prescribed value.SELECTED DRAWING: Figure 4
