WARMING SYSTEM AND HEAT SOURCE UNIT
Document Type and Number:
Japanese Patent JP2022135376
Kind Code:
A
Abstract:
To provide a warming system that enables control so as to prevent discharge pressure of a compressor from exceeding an upper limit value and enables improvement of reliability by suppressing failure or lowering of a service life of the compressor.SOLUTION: A hot water generation device 1 includes: a refrigeration cycle 20 comprising a compressor 21, a condenser 23, an expansion valve 24, an air blowing fan 26 and an evaporator 25 through which outdoor air passes by using the air blowing fan 26; a use side apparatus 31 that is a warming target; an annular medium flow passage 32 connecting the condenser 23 of the refrigeration cycle 20 and the use side apparatus 31 to circulate a heating medium; an outlet temperature sensor 13 detecting an outlet side temperature of the heating medium in the condenser 23; and a control section 5 setting an upper limit value of the outlet side temperature of the heating medium in the condenser 23 on the basis of a flow rate of the heating medium circulating in the medium flow passage 32 and controlling operation frequency of the compressor 21 in accordance with the upper limit value.SELECTED DRAWING: Figure 1
