what is the abstract of heat ventilation air conditioning system (HVAC)
Homework Answers
HVAC stands for Heating,Ventilating and air conditioning system.This type of system is majorly used in vehicles and households.It consists of mainly 5 parts as discussed below:
1)Outdoor unit: It provides fresh air to the unit.
2)Filter unit:this consists air filters which filter impurities like dust and larger particles and pollutants from air coming from outdoor unit.
3)Air return unit:It is sometimes called as starting point of HVAC.It has the fan which sucks the air from filters and pass it through the heating unit via ducts.
4)Heating unit:These may comprise of heating coils which heat up air coming from air return and further pass it through the duct to the required area.
5)Ducts:These are passage for air.

5. An HVAC (heating,ventilation, and air-conditioning) system in a house delivers warm air to various rooms in a house. A section of the ductwork (7” = 18 cm diameter duct) must pass through an unheated crawl space. This section of the duct is 8 m long. The air entering the duct has a mean temperature of 100F (38C) and a volumetric flow rate of 150cfm (0.07 m3/s). The house owner has insulated the duct with a 2 cm layer of...

A room is gaining 842 W of heat that needs to be removed by an air-conditioning system. Cold supply air is blown into the room and warmer return air is removed. What volumetric flow rate (in m3/s) of air is needed if the temperature difference between the supply and return air is 9 °C? Assume standard air density (1.2 kg/m3). Use specific heat of air = 1 kJ/kg-K.

Problem: The condenser in an air conditioning system is a heat exchanger in which cool air absorbs latent energy from the refrigerant, condensing the refrigerant from vapor to liquid. Refrigerant R-134 enters the condenser at 1 MPa and 90°C. It leaves the condenser at 1 MPa and 30°C. Cool air enters the condenser at 100 kPa and 27°C at a volume flow rate of 10 m3/s, and it leaves at 95 kPa and 60°C. Assume the specific heat of the...

A car air conditioning system takes air at 35 °C from the surrounding atmosphere and cools it down to 15 °C in a heat exchanger from which heat is removed by an ideal refrigeration cycle using refrigerant 134a. The condenser pressure is 1.2 MPa and the evaporator pressure is 0.2 MPa. If the car engine can supply 2 kW of power to run the air conditioner what is the maximum mass flow rate of cold air that can be supplied
