Answer: therefore the condenser deserve to properly disapprove heat there is no going right into a high system pressure, The types that need to be clean with chemicals are varieties that room not excusable
The greatest amount of warm that is offered up native the refrigerant is when the condensing procedure is taking place, de superheating
5.After heat is took in into a condenser tool in a water cooled condenser,the heat have the right to be deposited in one of two places.What are they?
Answer : The water have the right to be offered once, then wasted down the drain or where large amounts of water are being used, it is more economical to conserve water, cool that in an exterior water tower and also reuse it.

You are watching: When is the most heat removed from the refrigerant in the condensing process?

7.When a standard efficiency air cooled condenser is used the condensing refrigerant will typically be....F higher in temperature than the entering air temp .
Answer : High efficiency would be to have actually the condenser head pressure as close come the approximately air as possible.
Answer : The discharge gas can be passed to the rooftop condenser or to a coil mounted in the duct job-related that supplies heat to the store.
14.Briefly describe what is intended by floating head pressure and tell why that is used in refrigeration and AC system
Answer : An market term for attaining the lowest feasible condensing pressure is dubbed Floating head pressure. Floating head press systems simply let the condensing push follow the ambient temperature as the periods swing native summer to winter.
15.Explain exactly how to do the washing up impurities indigenous a water regulation valve that is on a water cooled condenser.
16.Explain the simple operations that a mix ORI and also ORD short ambient head pressure control valve.

Answer : ORD valve feeling a manufacturing facility preset pressure difference of 20 psi in between the receiver and also compressor discharge , the will begin to open and bypass hot compressor discharge gas come the receivers inlet The ORI valve stows refrigerant in the condenser to preserve the correct head pressure. Both the ORI and the ORD will work in conjunction of one one more to maintain appropriate receiver pressure, regardless of outside temperature.
17.Name two troubles a refrigeration device may have actually if the condensing unit is exposed to short ambient condition when it is not utilizing a short ambient head pressure regulate valve
Answer : as soon as the condensing tool is cold sufficient to reduce the head push to the point that the expansion maker will starve the evaporator. And also less head pressure reason less warm to be accessible for the warmth reclaim coils to heat buildings
