The article describes the stages of development of a laboratory installation for research and analysis of operational temperature and energy characteristics of refrigerated display cases with automated and non-automated control systems for cold set and thawing.
\nThe main elements of the developed laboratory installation are: 1) Refrigerating show-window of TATIANA 1.0NS type which components are systems: cooling, control, and thawing. 2) Processor control unit – Eliwell ID controller is equipped with a digital screen, has inputs for two temperature sensors RTS or NTC and three output relays to control the refrigeration compressor, fan and temperature process of the thawing cycle. The processor unit also provides control of the process of throttling the refrigerant in the evaporator to prevent water hammer in the motor-compressor of the refrigeration unit showcase 3) Flexible electric heater built into the evaporator to provide faster heating during automatic thawing. 4) System of forced air cooling of the condenser.
\nThe automatic control system with the processor control unit, which is implemented in the laboratory unit instead of the standard thermostat, provides precise temperature control in an extended range of cooling modes and cyclic thawing process. The showcase works in a stable and economical mode.
\nThe operating laboratory installation for research of parameters of the improved refrigerating show-window with the automated control system is developed and equipped. The laboratory refrigeration unit is equipped with devices for measuring and controlling electrical and energy parameters, temperature and humidity in the refrigeration chamber of the shop window during the study of cooling and defrosting modes.
\nWith an automatic control system in the shop windows, food products can be stored constantly without spending time on overloading them during the thawing of the evaporator.
\nThe developed operating laboratory installation can be used in the educational process for research and comparative analysis of operational temperature and energy characteristics of refrigerated display cases with automated and non-automated control systems for cold storage and defrosting.
\nKey words:<\/strong> laboratory installation, refrigerating show-window, constructive elements. automated control system, thawing process, temperature characteristics, throttling, boiler, hydraulic shock, temperature and energy characteristics<\/p>\n
