Cold store of new generation for carrots storage.

Summary

The paper presents the new generation of vegetable cold-storage equipped with the indirect refrigeration system and using the air coolers with the capacity regulation. In place of traditional on/off thermostat (located in the inlet air to the air cooler), the analogue thermostat (with capacity regulation) is applied in the outlet air from air cooler. The control system is based on the three-ways valve with the motor controlled by the analogue thermostat. The applied control system keeps the coolant temperature at the level which is required for the unsteady heat load of the air-cooler. The cold store has capacity of 10 000 tons of carrots and is used for a long-time storage. This cold-storage fulfils the requirements of the modern refrigeration technology: reduction of the refrigerant charge in the system, condensation heat recovery to defrost the aircooler and to heat the social-rooms, plastic piping, application of computerised system for control and supervising, and unification of the applied technical solutions. The technological benefits in terms of quality of stored carrots due to applied capacity regulation approach have been also discussed in the paper.
