THERMOSTATIC APPARATUS AND THERMOSTATIC AND HUMIDISTATIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a thermostatic apparatus and a thermostatic and humidistatic apparatus reduced in operation cost to a larger extent than ever and developing the same function as conventional one. SOLUTION: A part of a cooling medium compressed by a compressor 21 to be raised in temp. is cooled and evaporated to be sent to the cooler 22 of a thermostatic tank 10 and a part of the cooling medium raised in temp. is circulated to the heater 23 of the thermostatic tank 10 as it is to heat the thermostatic tank 10. A temp. control means controls the flow rate of the cooling medium to bring the thermostatic tank 10 to set temp. A return cooling medium control means controls the temp. and pressure of the cooling medium returned to the compressor 21 to constant values or less to ensure the normal operation of the compressor 21. A water spray means 24 is provided to the thermostatic tank 10 to control humidity.
