Electrical energy usage has been rapidly increased in the building sector due to shifting in population from rural to urban area. In the building, Heating, ventilation, and air conditioning (HVAC) system. Especially air-condition system has taken the most substantial proportion of overall building energy consumption. This result from a large amount of energy must be used in order to provide a comfort zone for occupants in the building. So, this paper aims to proposed design and built prototypes of air-condition control unit that can automatically operate according to schedule. The prototypes using a wireless module to send the control signal to the air-conditioning unit. Specific software has been built to set the desired operating schedule and duration of an operation. The performance of the proposed unit will be evaluated using an experiment on actual field test by installing on actual air-condition in the case study building. The result has shown that the proposed unit can reduce energy usage in air-conditioning significantly compare with little cost for the controller unit.

Fast Cooling

To implement the new generation thermo mechanical control process (NG-TMCP), the automatic control system of ultra fast cooling (UFC) was developed by combined with the renovation project of controlled cooling system in one plate production line. This system was composed of basic automation subsystem and process automation subsystem. As the main control unit of the basic automatic control system, a S7400 PLC system is used to control the UFC device and to achieve the chain control between the UFC system and the mill system. While the process control system is to realize the automatical setting of the cooling schedule by the developed finite element temperature field model and the temperature homogeneity model. The industry application shows that the NG-TMCP which is based on the UFC can reduce the alloy content effectively and implement the low-cost reduction produce of high-grade products.

Operational Temperature

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. The 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. The 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. The 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. With 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. The 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.
