HOW TO OPERAte a screw compressor and reciprocating compressors in series?
Your reciprocating compressors have to be the booster compressors (if running on low temp system)feeding its discharge to the suction of the screw(not directly)(if running on medium temp.
What pressure is medium pressure natural gas supplied?
medium pressure
Pressure rating black iron schedule 80?
What medium and temperature as there is something called "pressure temperature relationship"
Heat exchanger for ammonia absorption refrigeration system?
there are two type of heat exchanger in absorption refrigeration, first is liquid heat exchanger and other is gas heat exchanger.both heat exchanger function is same, to transfer heat (hot medium to cold medium) without violate second newton law of thermodynamics. liquids heat exchanger is between boiler and absorber vessel mean while gas heat exchanger between evaporator and absorber.
What is the maximum pressure schedule 40 galvanized pipe can take?
Need to know the pipe diameter. 3 inch is the diameter of the galvanized pipe what is the working pressure of the pipe
Why are intake ports on low- and medium- temperature compressors larger in size than intahe ports on air conditioning compressors?
To begin with the suction line is always larger than the discharge so it can facilitate the movement of the required volume of vapor, which because it is at a lower pressure is less dense so it needs more area (larger pipe). In a low or medium temp refrigeration system the suction pressure is lower still, so the gas is even less dense, thus even more area (larger pipe) is required. Additionally, as the design operating temp of the system is lowered so is the rated tonnage. Therefore a 20 ton freezer system will be physically larger than a 20 ton AC system.

What pressure is medium pressure natural gas supplied?
medium pressure
What is the temperature ranges for low medium and high refrigeration applications?
Low refrigeration applications typically range from -50°C to -18°C, medium refrigeration applications range from -18°C to 0°C, and high refrigeration applications range from 0°C to 10°C. These temperature ranges may vary depending on the specific requirements of the application and the type of refrigeration system being used.
The three temperature ranges for refrigeration systems are?
low temp, medium temp, high temp
Explain why an electric discharge occurs?
An electric discharge occurs when there is a build-up of electric charge in a medium that exceeds the medium's ability to insulate or contain the charge. This excess charge will rapidly move through the medium in the form of a visible discharge, such as lightning or a spark, to restore equilibrium.
What is dricold?
Dricold is the trade name for a liquid cooling medium used in refrigeration systems to absorb heat and lower the temperature. It is commonly used in commercial refrigeration and air conditioning units.
Does the frequency of a wave remain constant if the medium temperature and pressure do not change?
Yes, the frequency of a wave remains constant as long as the medium temperature and pressure do not change. Temperature and pressure affect the speed of sound in a medium, not the frequency of the wave.
What is pressure medium?
A pressure medium is a substance used in a system to transmit or apply pressure evenly. It can be a gas, liquid, or solid, depending on the system requirements. Pressure mediums are commonly used in hydraulic systems, pressure sensors, and industrial applications.
What do you need for a wave to occur?
A medium and a pressure differential
When a sound pressure wave propagates in a medium it creates areas of high and low pressures which are respectively known as?
When a sound pressure wave propagates in a medium, it creates areas of high pressure known as compressions and areas of low pressure known as rarefactions.
How many btus in a refrigeration hp?
Depends on evap temperature. It is then loosely placed in the low, medium or high category and assign a BTU/h equivalent.
