The application relates to the technical field of heat quantity detection, and particularly discloses an
oxygen bomb
calorimeter, a liquid path thereof and a liquid path
temperature control method. The liquid path of the
oxygen bomb
calorimeter comprises a
liquid storage tank, a first pump, a refrigerator, an outer
barrel, a second pump, a heater, a first valve, an inner
barrel and a second valve. The first pump and the refrigerator are connected between the outlet and the inlet of the
liquid storage tank. The second pump and the heater are connected between the inlet and the outlet of the outer
barrel. The first valve is connected between the first pump and the inlet of the outer barrel, and is used for connecting or disconnecting the first pump and the outer barrel. The second valve is connected between the first pump and the inlet of the inner barrel, and is used for connecting or disconnecting the first pump and the inner barrel. The liquid path and the liquid path
temperature control method of the
oxygen bomb
calorimeter can realize self-circulation
temperature control of the outer barrel and the
liquid storage tank, and the outer barrel and the
liquid storage tank can be controlled at different target temperatures respectively. During the test, the outer barrel does not participate in the test of the
liquid storage tank and the inner barrel, and the
test efficiency is improved. In addition, the liquid path structure is simple, and the number of parts is small.
