ASHRAE, based in 1894, is a world association of a few 50,000 individuals. ASHRAE fulfills its project of advancing heating, air flow, air-con, and refrigeration to serve humanity and advertise a sustainable international via study, criteria writing, publishing, and carrying on with schooling.

The ASHRAE Handbooks are the layout regular for keep an eye on of outfitted environments with volumes on structures and gear, HVAC purposes, Refrigeration and basics. each one is up to date each 4 years. as well as publishing layout suggestions for engineers, architects, and facility managers, we additionally put up a sequence of texts for lecture room use.

the various parts we put up in include:
-Energy Modeling and Auditing
-High functionality construction Design
-Psychrometrics
-Indoor Air caliber and Environmental Quality
-Data middle strength Efficiency
-Noise & Vibration Control
-Humidity Control
-HVAC for Healthcare amenities

Sample text

The drier is usually located in the liquid line near the liquid receiver. It may be mounted horizontally or vertically with the flange at the bottom, but it should never be mounted vertically with the flange on top because any loose material would then fall into the line when the drying element was removed. Strainers should be used in both liquid and suction lines to protect automatic valves and the compressor from foreign material, such as pipe welding scale, rust, and metal chips. The strainer should be mounted in a horizontal line, oriented so that the screen can be replaced without loose particles falling into the system.

Circulation of refrigerant through the evaporator depends on gravity and a thermosiphon effect. A mixture of liquid refrigerant and vapor returns to the surge tank, and the vapor flows into the suction line. A baffle installed in the surge tank helps prevent foam and liquid from entering the suction line. A liquid refrigerant circulating pump (Figure 17) provides a more positive way of obtaining a high circulation rate. Taking the suction line off the top of the surge tank causes difficulties if no special provisions are made for oil return.

Figure 21 shows an example of connections for a surgetype receiver. Height h must be adequate for a liquid pressure at least as large as the pressure loss through the condenser, liquid line, and vent line at the maximum temperature difference between the receiver ambient and the condensing temperature. Condenser pressure drop at the greatest expected heat rejection should be obtained from the manufacturer. The minimum value of h can then be calculated to determine whether the available height will allow the surgetype receiver.
