Fire safety

Fire safety is a new domain emerged in the early 90s to enable the design of buildings, structures, and infrastructure against destruction through fire. It also includes the provisions of building codes. This field is mostly associated with the design and efficient planning of a building, to reduce the destruction caused by fire. The branch of engineering that deals with it for the safety of the buildings from destruction of fire, is known as fire safety engineering.

Q1. Solve all parts Depicted in Fig. Q1 is an irreversible refrigerator whose compressor is powered by a reversible heat engine that operates between temperature extremes Thot = 473K and cold = 293 K. The refrigerator depicted uses a dichlorodifluoromethane refrigerant (Refrigerant 12) circulating by means of the compressor at mass flow rate = 0.15 kg/s. The other components of the refrigerator are two heat exchangers in the form of an evaporator and a condenser, and a throttle valve. Information recorded at the state points depicted in Fig. Q1 is as follows: State point 1: dryness fraction x₁ = 1 and temperature t₁ = 15 °C. State point 2: dryness fraction x2 = 0 and temperature t₂ = 15°C. State point 3: wet vapour at temperature t₁ = -20°C. State point 4: wet vapour at temperature t₁ = -20°C.

H6. An air conditioner in an upper-floor apartment unit is turned on during a hot summer afternoon. If heat can be removed from the interior at a rate of 1.5 kW, estimate the time required to cool the air inside the apartment to its final temperature. Your estimate should create any needed input data and should incorporate factors like the size of the apartment and the behavior of air.
A window-mounted air conditioner removes 2.1 kJ from the inside of a home using 1.75 kJ work input. What is its coefficient of performance? Note: thermodynamically, and air conditioner is the same thing as a refrigerator - it makes the inside of a container (house, refrigerator) colder.
A heat pump is used to meet the heating requirements of a house and maintain it at 20°C.
