Design Of Systems, Perimeter
After the loss of heat or heat revenue, the amount of these losses or gains will determine the amount of duct systems, heating and cooling systems. Three factors that ensure proper delivery and distribution of air within the same premises are in the place of exit, socket type and size of the output. Supply socket if possible, should always be placed so that the blanket every window and every outer walls (see Fig. 17-5). Therefore, encouraged to register under every window.
The output must be selected using a diffuser, whose air fan-shaped pattern blanket bare walls and Windows. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) represents the chart and load factors are necessary for climate in every major city in the United States. The chart should be carefully studied. The type of house, construction materials, home location, room size, and exposure to the sun and wind are important factors.
With this information, you can determine how much heat will be dissipated. You can also determine how much heat will be lost in the building. You can also specify how many cooling will be lost in the building. ASHRAE Handbook of Fundamentals lists the information necessary for calculating the load factors.
Calculation of heat loss and heat gain the room; divide this figure by the number of sockets for installation. From this you can determine BTU per hour required for each socket. Please see the performance data provided by the manufacturer to determine the size of the output should be. For residential applications, selected size should be large enough so Btu / hour on the chart falls to the side, where quiet area indicated. There are still minimum vertical throw 6 feet, where cooling is involved.
