What is condensing temperature for a head pressure of 175 psig for an R-12 system?
75 or 80
Low condensing pressure?
Low condensing pressure is usually the most misunderstood and hardley ever used freezer and fridge settings. You do not want to have a high condensation pressue on your fridge or freezer. This is easy to fix but many do not even understand what it means.
How does pressure affect temperature?
as pressure increases, temperature increases
Where is the purge unit located in a low-pressure system?
The purge unit is located at the condenser.
Where does the refrigerant go after it leaves the purge unit of a low pressure centrifugal systems?
condenser
What is the condensing pressure of 260 psig and the condesor outlet temperature is 100 degrees for r-22y how many degrees is the liquid subcooled in the condenser?
7 F
If the condensing pressure is 260 psig and the condensing outlet temperature is 108 degrees. what is the sub cooling in the condenser?
12
What is the refrigeration cycle?
First step in refrigeration is evaporation. The next step is compression, which raises the pressure of the refrigerant vapor. Condensing is the third step and is where the heat transfer takes place. Expansion is the fourth step and is where the condenser cools the refrigerant even more, to a level below the condensing temperature.

Function of a condenser?
The condenser receives hot high pressure gas refrigerant from the air conditioning compressor.It cools this gas (it looks like a radiator) turning the gas into a cooler liquid. (condensing it)
What temperature is the condensation temperature of ammonia?
The temperature varies with its pressure. If pressure high the condensing temperature also high. please be more specific, can someone please provide more specifics to this?
What is the component of a refrigeration system which changes a high pressure vapor to a high pressure liquid?
A brief discussion of the operating vapor-compression cycle is helpful to indicate other potential refrigeration problems in real systems. In the basic cycle, slightly subcooled refrigerant leaves the condenser at high pressure and flows into the liquid receiver if one is present. The refrigerant then enters the throttling device (capillary tube, TXV, etc.) where the pressure is dropped. It then enters the evaporator as a two-phase mixture (liquid and vapor) and evaporates or boils at low temperature, adsorbing heat. Slightly superheated refrigerant vapor exits the evaporator and enters the suction line accumulator, if one is present (used to trap any transient liquid slugs). The refrigerant vapor then enters the compressor where the pressure and temperature are increased as the compressor compresses the refrigerant vapor. The vapor leaving the compressor is superheated, and the compressor discharge is the hottest point in the cycle. This refrigerant is cooled and condensed in the condenser where heat is rejected, and the refrigerant is condensed to liquid. Refrigerant actually leaves the condenser slightly subcooled (subcooled liquid) to assure condensation has been complete. Any non-condensable vapors in the system will be unable to condense in the condenser and will appear as gas bubbles in the condensed liquid stream. These non-condensables may collect in the condenser and displace refrigerant from the condenser heat exchanger, thereby reducing the effective surface area of the condenser.The compressor changes the low pressure vapor to high pressure vapor sending it threw the condenser to cool and turn it back into liquid.

What is difference bw condensing and non condensing steam turbines?
A condensing turbine uses all the energy from the steam going from high pressure turbine to secondary turbine to condensing turbine then sends the condensate back for reheating. where a non condensing turbine just uses the high pressure aspect of the steam then returns the low pressure stream back to be reheated. Condensng turbines utilises the entire available drop from high pressure to the vacuum in the condenser; a back pressure turbine only utilises only the top part, whereas an exhaust steam turbine utilises only th bottom part of the pressure drop. Hope that helps.
How do you make the air condenser work?
An air condenser takes in the surrounding air(at about 45-50 degree Celsius). The vapor at high pressure enters the condenser and accepts the latent heat of condensation from the hot airthereby rejecting heat to condensing coils. The vapor then becomes liquid.
Why is vacuum in the condenser of such importance?
If you are talking about a condenser attached to a steam turbine, then a vacuum is important because it extends the usefulness of the steam in the turbine. As you probably know, steam begins to condense back into water at 212 deg at atmospheric pressure. However, in a vacuum condition, the boiling and condensing temperature is lower. Because the condenser is under a vacuum, steam exits the turbine and enters the condenser around 130 deg. This results in more power (mega watts).
What is the condensing pressure?
According to state of the outlet refrigerant from compressor, it's better we use refrigerant temperature.
