This project is based on the design and construction of an industrial air conditioning system for the improvement of the working thermal comfort of workers that for various reasons there is the trend of the increase in body temperature are these by machines, equipment or the same work activities, which affects the productive performance and possible health risks. During development, the selection of mechanical equipment such as the fan, water pump, ventilation transport ducts is studied with high rates of energy efficiency. In the light of the above, the environmental economic partner alternative is chosen to implement the evaporative conditioning system, conducive to working in open places to lower the temperature by labor and technology installed in the production areas, as well as the extraction of fumes derived from production processes. The importance of the evaporative conditioning system is to derive the appropriate mechanisms to take advantage of the surface heat transfer of a panel and copper and aluminum coil using water, and thus take advantage of its temperature differential reaching 25oC, with an average humidity of 66% and energy consumption of 0.29 KW/h.

The present study of a freezing system has developed based on an air conditioning system, whose purpose is to take advantage of the technological transfer of cold producing equipment for food storage and conservation uses. The installed capacity of 9000 BTU/Hr was considered for the choice of equipment. We studied the freezing process of fish, water, and the preservation of legumes with a volume of 1 kg per product individually. The freezing temperature has evaluated with a mechanical compression refrigeration system of Gas R22 with temperature interactions of 29.6 ° C to -12 ° C. and monitored with a Proportional Integrative Derivative (PID) controller. For production cost, the equipment was mostly made of its parts and pieces with recycling material. A descriptive experimental design has carried out, for the verification of results. The equipment managed to reach chamber temperatures of -13 ° C from 20 minutes once the equipment (compressor) has turned on under specific product descriptions.

The design and construction of a cold production system from the ice water submitted by a mechanical direct expansion system contributing to the development of knowledge in the area of air conditioning were carried out. Among the technical design parameters, a direct expansion system with cooling capacity of 9000 BTU/Hrs, R134 refrigerant gas to a turbine for the work of the Fan Coil of ½ Hp of force 220 V was selected, as was the fan motor of the cooling tower as fundamental means for heat transfer. The recirculation pumping system is carried out by pumps of 0.37 kW of power and a maximum flow of 40 l/min. For both the evaporator sump (cold) and the condenser sump (hot). The work stage is given in two independent circuits, the Fan Coil system is connected to the evaporator sump and the cooling tower, in turn, is connected to the condensation system for proper operation and achieve condensation temperatures of 35 ° C and in case of having water requirements in the cold sump, the tower is connected by means of an electromagnetic valve for its supply.
