Air refresher is a process of cooling the air so that it can reach the appropriate temperature and humidity required for the air condition of a certain room. The purpose of this study is to calculate the heat load in the design and construction laboratory of the mechanical engineering department, Faculty of Engineering, Halu Oleo University. The method used in this study is an analytical method by calculating the cooling load on each predetermined parameter, namely on walls, roofs, windows, doors, as well as lighting, electronic equipment and occupants. This calculation is carried out every hour from 08.00 to 17.00 local time. The results showed that the cooling load increased significantly from 08.00 until the peak occurred at 13.00 to 14.00, then the cooling load began to decrease significantly at 15.00 to 17.00. The high cooling load that occurs at 13.00 and 14.00 is thought to be due to the sun's rays coming at a vertical angle so that the heat received is greater than in the afternoon or evening where the angle of incidence of the sun's rays is tilted.Keywords: Air refresh, Cooling load

The hatching machine is one of the media in the form of a box with such a construction that the heat inside is not wasted. This incubator is equipped with supporting equipment to regulate environmental conditions similar to or similar to the broodstock. The purpose of this study is to determine the effect of the use of a layer of aluminum foil on the walls of the egg incubator on the resulting hatchability. This research was conducted by installing an incubator, then testing it using an incubator. Data were collected by measuring room temperature, room humidity, light on and off, and checking embryo development. The results showed that the egg incubator without aluminum foil layer began to hatch on the 20th day as many as 3 eggs, and on the 21st day as many as 4 eggs so that the eggs hatched were 7 out of 10 eggs and for the egg incubator with a layer aluminum foil hatched early on the 19th day as many as 2 eggs, on the 20th day as many as 3 eggs and on the 21st day as many as 4 eggs so that the eggs hatched were 9 eggs out of 10 eggs. The use of aluminum foil in the egg incubator affects the hatchability.Keywords: Egg incubator, aluminum foil coating, hatchability.
