A lab. unit consisting of a heat source, an oil cooler, a 2-way pump, an evaporator of MeOH with the pressure measurement transducer and the MeOH condenser was constructed. The unit was coupled by the system of valves with 2 absorbers equipped with MeOH-activated C sorption sets, operated periodically in the opposite system. Instantaneous values of the temps. at the cooling water inlet and outlet in the evaporator, the water mass flow and oil temps. at the adsorber inlet and outlet and the mass flow of oil were measured. Cooling power, thermal power and efficiency ratio of adsorption refrigerating were detd.
