RESUMO

Innovative approach to regulate operation temperature of LHP with two –way valve is discussed. Comparison with traditional three-way bypass valve is done. It was investigated that two-way valve design provides better ability of thermal control as traditional three-way design and has significant advantages. Some examples of two –way valve application is presented. Heat transfer limitation of LHP with PRV was verified. Both modes of PRV application demonstrated practically the same maximum heat transfer rate of LHP. It was also obtained that maximum heat transfer capacity of LHP with valve is higher than for LHP without valve. Start up ability of LHP with and without PRV was compared. It was found that PRV can facilitate start up.
