In the summer time, the heat of the sun forces its way indoors. Inside industrial premises, especially in warehouses and workshops, which are not equipped with air conditioning, employees are exposed to excess heat. The temperature prevailing inside the premises is usually higher than that outdoor temperature due to the heat emitted from various production machinery, a large number of people working together, lighting equipment and other factors. This leads to reduced productivity, increased number of production mistakes, deteriorating wellbeing of the employees and increasing risk of health disorders.
A sewing shop is located on the top fl oor of a fi vestorey building. The area of the shop is about 2,000 m2; the ceiling height – 5 m; the number of people working in the shop – 150. The building is an old construction; the thermal insulation of the premises is limited; the large windows face the South and West. The sewing shop houses a lot of heat producing equipment: ironing devices, sewing machines, lighting is on continuously. These generate great amount of heat in the sewing shop in hot season. The indoor temperature used to be 35°C or more. In case of high temperature outdoors (~30 °C), natural ventilation of the premises by opening the windows was no longer effective. High indoor temperature and shortage of fresh air had negative effect on the employees’ wellbeing: the heat made them feel exhausted, it was diffi cult to breathe, the productivity decreased, the number of mistakes increased, etc. To solve the problem, 6 evaporative air coolers ColdAir have been mounted on the roof. The microclimate in the premises has improved signifi cantly: the indoor temperature has cooled down by 6 to 8 degrees and the shortage of fresh air has been eliminated at the same time. The employees are happy about the improved conditions and excellent working atmosphere.
