Answer: so the condenser can properly disapprove heat there is no going right into a high mechanism pressure, The types that have to be clean with chemicals are varieties that room not excusable
The greatest amount of heat that is provided up native the refrigerant is if the condensing procedure is taking place, de superheating
5.After warm is absorbed into a condenser medium in a water cooled condenser,the heat can be deposited in among two places.What space they?
Answer : The water have the right to be provided once, climate wasted down the drain or where large amounts the water space being used, it is an ext economical to conserve water, cool that in an external water tower and reuse it.

7.When a standard efficiency air cooled condenser is used the condensing refrigerant will normally be....F greater in temperature than the entering air temp .
Answer : High effectiveness would it is in to have actually the condenser head press as close come the approximately air as possible.
Answer : The discharge gas have the right to be passed come the rooftop condenser or to a coil an installed in the duct job-related that supplies warm to the store.
14.Briefly define what is expected by floating head pressure and also tell why the is provided in refrigeration and also AC system
Answer : An market term because that attaining the lowest possible condensing push is called Floating head pressure. Floating head pressure systems simply let the condensing pressure follow the ambient temperature as the seasons swing indigenous summer to winter.
15.Explain how to flush impurities native a water regulating valve the is top top a water cooled condenser.
16.Explain the simple operations of a combination ORI and ORD low ambient head pressure manage valve.

Answer : ORD valve sense a factory preset pressure distinction of 20 psi between the receiver and also compressor discharge , it will begin to open and also bypass hot compressor discharge gas to the receivers inlet The ORI valve stows refrigerant in the condenser to maintain the correct head pressure. Both the ORI and also the ORD will occupational in connect of one another to maintain suitable receiver pressure, regardless of exterior temperature.
17.Name two troubles a refrigeration system may have actually if the condensing unit is exposed to low ambient problem when that is not making use of a short ambient head pressure regulate valve
Answer : when the condensing medium is cold sufficient to alleviate the head push to the point that the expansion an equipment will starve the evaporator. And less head pressure cause less warmth to be available for the warm reclaim coils to warm buildings
20.What need to be included to the device to aid water when it is evaporating from end concentrating minerals ?
