Design and construction of a cold production simulator system: chiller

Abstract

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.

Chiller Carrier: Costos de Aplicación del Mantenimiento Centrado en la Confiabilidad

“…Dado que, en la actualidad, sistemas como este no son cuestión de lujo, sino una necesidad que atender ya que de un ambiente climatizado depende en gran porcentaje la productividad industrial o empresarial (Nieto, 2021); en este sentido, el chiller o unidad Vicente Sánchez-Ruiz | Galvin Toala-Arcentales | pp. 204-213 generadora de agua helada representa más del 60% del consumo total de todo el sistema de enfriamiento, por tratarse de un equipo que en virtud del principio basado en el ciclo de refrigeración (Nájera, 2021), usa refrigerante como parte fundamental de su operación y cuya eficiencia impacta directamente en las emisiones generadas, convirtiéndose en una alternativa ecoamigable para producir confort térmico en la industria en general (Muñoz & y Macías, 2019).…”

Design and construction of an industrial ship conditioning system

“…Executive Decree 2393 of the Workers' Safety and Health Regulation in Article 54 tells us that in working environments due to the effect of machines and work in production processes should not exceed the maximum permissible temperature values for the worker who is between 35 and 37 o C, and if this temperature has to increase from incorporating insulators for the reduction of the heat of the machines or implementing air conditioning systems in the enclosures (IESS, 1986). In the summer season, high temperatures are specifically reached, in industrial activity as in social services, around 34oC average heat, the temperature of the enclosure between 20 and 27 o C and humidity between 30 and 70%; smoke and general environmental characteristics characterize hard working hours and tiredness achieving the decrease in the production of workers, these aspects being important to solve to achieve an adequate level of competitive products and also respond to local and international environmental legislation (Company, 2016). On the other hand, it is important to mention that these evaporative systems fulfill the function of aerators and coolers in production areas (Flores et al, 2011), with high-efficiency parameters correlating with energy efficiency regulations by the European Commission (Olivares, 2017;Kuznik et al, 2008;Sun et al, 2004;Martens, 1998), which is essential in many cases for the generation of gases products from manufacturing processes which in turn makes potential sinks dangerous to health.…”
