Comparison with a traditional three-way bypass valve is presented. It is found that a two-way valve design provides better thermal control than a traditional three-way design and has significant advantages. Some examples of two-way valve application are presented. Heat transfer limitation of an LHP with a pressure regulating valve is verified. Both modes of pressure regulating valve (PRV) application demonstrate practically the same maximum heat transfer rate. It is also found that the maximum heat transfer capacity of an LHP with a PRV is higher than an LHP without a valve. The start-up ability of an LHP with and without a PRV is also compared. It is observed that the PRV can facilitate the LHP start-up. %8 2012-05-18
