Abstract

COP on a cooling machine is used to reveal the performance of a cooling engine. To increase the COP value in the system, it can be done by changing the dimensions of the filter-drier and capillary pipes used. Therefore, this study was conducted to determine the effect of changing the dimensions of the filter-drier and capillary pipe on the COP and the consumption of electrical power produced by the 2-door refrigerator unit. The method used was an experimental method, namely by varying the filter drier and capillary tube dimensions of the 2-door refrigerator. Variations of filter driers used were filter driers with sizes 7 cm and 9 cm. While the capillary pipes used were 0.31 inches in diameter and 0.51 inches in diameter with a length of 200 cm and 250 cm respectively. The results obtained from this study indicate that the greatest COP value is obtained when using a 7 cm filter-drier and a capillary pipe with a diameter of 0.31 inches with a length of 200 cm, which is 2.80. The COP value also continues to decline as the size of the filter-drier and capillary pipes used increases.

Abstract

The amount of plastic waste each year will increase by 10% every year which is a problem for a country. Therefore, proper processing of plastic waste needs to be done. Before being processed into plastic waste processing, it is necessary to have a chopping process using a plastic chopping machine. The plastic chopping machine has an important component, namely the chopping knife. Before carrying out the knife manufacturing process, it is necessary to validate the design of the blade that is used with its loading. Model simulation using software is one way to quickly validate the model. This study aims to determine the effect of loading variations on stress, strain, deformation and safety factors of the model. The use of ANSYS R17.2 software is used to analyze the chopping machine knife model with a variation of 5kg / hour, 10kg / hour, 20kg / hour and 50kg / hour capacities. The result is that the stress, strain and deformation parameters have an increase in value with increasing loading variations. The greatest values of stress, strain and deformation are in the variation of 50kg / hour respectively 64.995 Pa; 336.76 and 56,358 x 10-11mm. The value of the safety factor for all variations of loading has a value of 15. The value of the safety factor means that the design of the plastic chopping knife is safe to use up to a loading of 50kg / hour

Abstract

Refrigeration is an attempt to maintain the temperature level of a material or room at a level lower than the temperature of the surrounding environment by absorbing heat from the material or room. In short it can be said that refrigeration is the process of transferring heat from a material or another room. Basically, refrigeration technology is heat treatment. The refrigeration process is inseparable from the cooling load problem during the refrigeration machine operates. Excessive cooling load on a refrigeration unit will certainly have an effect that can accelerate the process of decomposition or deterioration in the quality of the catch. This research aims to calculate the cooling load of the blast freezer water and determine the refrigeration components of the blast freezer water unit. From the research results obtained, that the ship whose refrigeration system has a cooling power of 30 kW is able to cool fish as much as 3.5 tons (3,500 kg). With a cooling load of 1 ABF space of 28.54 kW with a fish mass of 3,500 kg. the COPactual achieved by the blast freezer water is about 2.8 smaller than the COPcarnot of 6.1.
