Title: Adsorptive type freezer
Inventor: KASHIWABARA YOSHITAKA
IPC: F25B17/08
Filed: 1994-11-08
Abstract: PURPOSE: To improve a heat recovering efficiency from a regenerated heat exchanger to an adsorptive heat exchanger by a method wherein after water passed through the regenerated heat exchanger is flowed into a coiled tank, the water is flowed out in a reverse direction and passed through the adsorptive heat exchanger. CONSTITUTION: A coiled tank 6 is used for temporarily storing water recovering heat while passing through a regenerative heat exchanger A. Flow passage is changed over to a cooling water passage and a hot water passage by valves v1 to v15 in such a way that extremity ends of series of water heat recovered and flowed into the coiled tank 6 may become the most-last ends when they are flowed out. Accordingly, an adsorptive heat exchanger B is heated at first with a low temperature part of the series of water (about 50 deg.C to 70 deg.C), thereafter the water is heated with a high temperature part (about 70 deg.C to 85 deg.C), resulting in that a sufficient temperature gradient may be attained between the series of water and the heat exchanger B throughout the entire period of preheating cycle and so an effective heat exchanging can be carried out.

Filed: 1986-12-17
Abstract: PURPOSE:To analyze bromine simply, by a method wherein sodium hydrogen sulfite is added to a bromine aqueous solution coexisting with chlorine to generate ions of chlorine and bromine under non-release condition and bromine ions are determined by iodine titration. CONSTITUTION:Sodium hydrogen sulfite is added to an aqueous solution containing chlorine and bromine and after the stop is put immediately, they are mixed thoroughly to form chlorine ions and bromine ions.
