Abstract

Air conditioning for residential comfort is important for human life for the early days of the changing weather climate that affects the temperature of the air temperature in residential dwellings. The air conditioning system is one of the business actions in the form of maintaining the temperature level in the room from the low level of the ambient temperature around it by absorbing heat from the material or room. The air conditioning load is also carried out to determine the AC capacity needed. Research conducted by the Glamour Mansion Tanjung Morawa Housing Complex using the method used is to calculate cooling capacity based on GA (General Arranggement) which includes several parameters, namely the number of people, number of windows, room volume, equipment, and heat from lights. So that the calculation of Heat Calculation, Air Capacity, and Cooling Capacity in a complex is obtained. From the results of the study it is known that the AC cooling load for the Glamour Mansion Tanjung Morawa Complex is the living room 1482 BTU / h, Room I 1953 BTU / h, Room II 800 BTU / h. 1 AC with a capacity of ½ PK in the room. 1 AC with a capacity of ½ PK in each room.

Abstract

The Basic Electrical Engineering Laboratory of Medan State University uses many nonlinear loads such as computers, laptops, printers, scanners, projectors, inverters, converters and others that can cause harmonics. The method used to overcome harmonics is by using a double tuned passive filter, the use of a double tuned filter has an effect on reducing current harmonics and overcoming the increase in cos phi values ​​in the electrical system. A double tuned filter can be a broader strategy in managing power factors by reducing certain harmonic orders, but it cannot directly improve the overall power factor without carefully considering the system conditions and existing problems. By inputting the filter requirement values ​​F,,, , Ω the simulation results obtained are a decrease in harmonic levels, where the third order harmonic which was originally 28.3% fell to 19.77% and the fifth order harmonic which was originally 13.27% fell to 9.27%. The reliability of using a double tuned filter to increase the desired power factor of 0.95 by compensating for the known reactive power of Qc = 794.206846 Var. The use of passive filters is very feasible to be used in reducing harmonic disturbances that occur in the electric power system.
