Hello Can you please explain this question to me I don't want the solution i just want to know what to do to slolve it? one-storey building with building construction is of medium insulation and mass. The air change per hour through the building is assumed to be ACH. The inside and outside design temperatures are 22 C and 4 C respectively. Occupants are 6 people, each uses 50 L/person/day of hot water. There are appliances in the building which produce a total internal heat gain of W. Windows are of sliding type. 200 Ahot water heating system is to be used of a forced thermoplastic piping type. Assume water temperature difference across each radiator as 10 C Sketch the designed heating system on the building plan view provided, and calculate the followings: a) The heating load of the building, using tobulated format for each space b The total heating load of the building The capacity of a suitable boiler, which includes the capacity of the hot water cylinder d) The capacity of the pump in (LA) and pressure head (m) e) The diameter of all supply and return pipes f The diesel fuel consumption and volume ofits tonk assuming the efficiency of the boiler as 82%, and the calorific value of diesel used as 40,000kWkg and its density as 850 g) The diameter of the boiler chimney the flue gas density andits average velocity are assumed as 1.10kg/ma and 4 m/s, respectively The surface areasandU-values of the building, and other data areas given in the Table below House Component Quantities Exterior walls Net area walheight 3m 1725 ma 38 mm on grade Total exposed surface 331.5 mi walgoss area plus roof area 517.5 ma Assume other values if required. Use ASHRAE tables to obtain other related parameters if necessary. Guestroom 3moeling heigtthroughout

Explanation / Answer

due to temprature diffrence and hot water requuirement some heating load will come yhat u have to calculate based on thermodynamics.

then you have to design the boiler (capacity according to requirement of water and energy ) ,pumps according to requirement of water flow and then pipes according to flow and require head
