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

The ASHRAE Handbooks are the layout common for keep watch over of outfitted environments with volumes on platforms and gear, HVAC functions, Refrigeration and basics. every one is up to date each 4 years. as well as publishing layout information for engineers, architects, and facility managers, we additionally post a chain of texts for lecture room use.

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

18 Double Hot-Gas Riser Fig. 16 Flooded Evaporator (Gravity Circulation) Fig. 17 Flooded Evaporator (Forced Circulation) below the liquid level in the surge tank (where an oil-rich liquid refrigerant exists). They extend to a lower point on the suction line to allow gravity flow. Included in this oil return line is (1) a solenoid valve that is open only while the compressor is running and (2) a metering valve that is adjusted to allow a constant but small-volume return to the suction line. A liquid-line sight glass may be installed downstream from the metering valve to serve as a convenient check on liquid being returned.

They are good for use as liquid subcoolers. For air-conditioning applications, heat exchangers are recommended for liquid subcooling or for clearing up excess liquid in the suction line. For refrigeration applications, heat exchangers are recommended to increase cycle efficiency, as well as for liquid subcooling and removing small amounts of excess liquid in the suction line. Excessive superheating of the suction gas should be avoided. Two-Stage Subcoolers To take full advantage of the two-stage system, the refrigerant liquid should be cooled to near the interstage temperature to reduce the amount of flash gas handled by the low-stage compressor.

The discharge line pipe size into and out of the oil separator should be the full size determined for the discharge line. For separators that have internal oil float mechanisms, allow enough room to remove the oil float assembly for servicing. Depending on system design, the oil return line from the separator may feed to one of the following locations: • Directly to the compressor crankcase • Directly into the suction line ahead of the compressor • Into an oil reservoir or device used to collect oil, used for a specifically designed oil management system When a solenoid valve is used in the oil return line, the valve should be wired so that it is open when the compressor is running.
