ASHRAE, based in 1894, is a world association of a few 50,000 individuals. ASHRAE fulfills its undertaking of advancing heating, air flow, air-con, and refrigeration to serve humanity and advertise a sustainable global via learn, 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 kit, HVAC purposes, Refrigeration and basics. every one is up-to-date each 4 years. as well as publishing layout suggestions for engineers, architects, and facility managers, we additionally submit a sequence of texts for lecture room use.

many of the components we submit in include:
-Energy Modeling and Auditing
-High functionality construction Design
-Indoor Air caliber and Environmental Quality
-Data heart power Efficiency
-Noise & Vibration Control
-Humidity Control
-HVAC for Healthcare amenities

Example text

Check valve in the vent with flow in the direction of the condenser. 5 psi). When determining condensate drop leg height, allowance must be made to overcome both the pressure drop across this check valve and the refrigerant pressure drop through the condenser. This ensures that there will be no liquid back-up into an HEAT EXCHANGERS AND VESSELS Receivers Refrigerant receivers are vessels used to store excess refrigerant circulated throughout the system. Their purpose is to • Provide pumpdown storage capacity when another part of the system must be serviced or the system must be shut down for an extended time.

Because the crankcase heater remains energized during the complete off cycle, it is important that a continuous live circuit be available to the heater during the off time. The compressor cannot start again until the temperature control device or manual control switch closes, regardless of the position of the low-pressure switch. , high-pressure cutout, oil safety switch, and motor overloads), so that the refrigerant flow valve closes when the compressor stops Control for Direct-Expansion Water Chillers Automatic pumpdown control is undesirable for direct-expansion water chillers because freezing is possible if excessive cycling occurs.

Piping to Prevent Liquid and Oil from Draining to Compressor Head. Whenever the condenser is located above the compressor, the hot-gas line should be trapped near the compressor before rising to the condenser, especially if the hot-gas riser is long. This minimizes the possibility of refrigerant, condensed in the line during off cycles, draining back to the head of the compressor. Also, any oil traveling up the pipe wall will not drain back to the compressor head. The loop in the hot-gas line (Figure 19) serves as a reservoir and traps liquid resulting from condensation in the line during shutdown, thus preventing gravity drainage of liquid and oil back to the compressor head.
