TEMPERATURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2015129598
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suitably avoid a case where lubrication failure occurs in a compressor at operation start time under an extremely low temperature environment.SOLUTION: A control unit, at operation start time of a temperature control device, starts an operation of a compressor (Step 22a), and performs closing control of an opening/closing valve (Step 23a), and when standby time which is regulated in advance has elapsed since the start of the operation of the compressor (Step 24a), it determines whether or not a first low temperature time processing start condition regulated in advance is satisfied (Step 26a), and when the first low temperature time processing start condition is satisfied, it executes the first low temperature time processing in which a refrigerant discharged from the compressor by performing opening control of the opening/closing valve is flowed into an evaporator via bypass piping (Step 27a).
