This paper presents a novel automated wind chiller hybrid cooling system applied to a cold storage room. The objective of the new hybrid system is to utilize less electricity from the grid by using a wind chiller setup. The dimensions and cooling load of a typical cold storage room was defined based on the requirements of the Philippine environment. Various cold storage parameters were listed and calculated to fully define the typical cold storage room. An automation system was designed using ladder logic programming to identify the usage of the wind chiller in hybrid with a conventional electric cooling system. The rotational speed of the wind chiller was the primary parameter in accessing the usage of the wind chiller or the electrical cooling system. The automation included lubrication to ensure optimal wind chiller rotation. Equipment for automation implementation were suggested in the study. Simulations showed that the proposed program can control the utilization of wind chiller or the electrical cooling system for optimal performance. Results show that a potential savings of USD 4,860 can be achieved in a year.
