The superheat must be removed first before the refrigerant can condense. This occurs in the first portion of the condenser known as the desuperheating section .
What process takes place in condenser?
A condenser is designed to transfer heat from a working fluid (e.g. water in a steam power plant) to a secondary fluid or the surrounding air. ... As this process occurs along the condenser, the quantity of vapor decreases and the quantity of liquid increases; at the outlet of the condenser, only liquid remains.
What is the first function a condenser must perform?
| Question Answer | 33-the first function a condenser must perform is to _____the refrigerant before condensing can occur. de-superheat | 34-a thermostatic expansion valve is design to maintain; constant evaporator superheat | 35-the automatic expansion valve is design to maintain constant evaporator pressure |

What 3 actions take place in the condenser?
- Desuperheating. Refrigerant exits your evaporator coil as a gas, having absorbed heat from inside of your home. ...
- Condensation. ...
- Subcooling.
What does the condenser do quizlet?
What is the purpose of a condenser? The purpose of a condenser coil is to reject unwanted heat from a refrigeration or air conditioning system . It does this by condensing the high pressure, high temperature gas to a liquid.
What is the purpose of using a condenser?
What is the purpose of using a condenser? Explanation: Condenser is used to convert vapor refrigerant discharging from the compressor into liquid refrigerant by rejecting or removing heat and attaining the saturated liquid line for the refrigerant .
What are the three phases of the condenser?
What are the three phases of the condenser? De-superheat, condense, and subcool .
How do I know my condenser capacity?
– The formula for the capacity of condenser is given by C=Ad When A is the area of each plate and d is the distance between the plates .
How do you make a condenser?
- Determine suitable types of condensers. ...
- Determine the heat load.
- Select the coolant temperatures and calculate an overall logarithmic mean temperature difference.
- Estimate an overall coefficient from Table 1 or by prior experience using estimated individual coefficients.
Which type of condenser is used in domestic refrigerator?
Natural convection type :
As a result a relatively large condensing surface is required to reject a given amount of heat. Hence these condensers are used for small capacity refrigeration systems like household refrigerators and freezers.
What 3 materials are condensers made of?
The most common tube materials in a condenser are copper–nickel alloys, brass, titanium, stainless steel, and ferritic stainless steel .
What do condenser fins do?
The condenser fins are thin metal slats that run along the outline of your exterior AC unit. The purpose of the condenser fins is to move warm air away from the air conditioner while it's running .
What part of the air conditioner is the condenser?
The outside portion of your air conditioner is most often referred to as the “condenser unit.” Whereas the inside part of your air conditioner is responsible for absorbing heat from your home's air, your outside unit's job is to release that heat to the air outside.
Which type of condenser uses a fan to push air across the condenser?
An air-cooled condenser uses fans to blow cooler ambient air across the coils through which the system's refrigerant runs, a process that cools that fluid enough to allow it to cool the evaporator plate.
Which type of condenser requires the most maintenance?
Equipment Maintenance
Evaporative condensers require more maintenance than air-cooled condensers.
What type of water cooled condenser can be taken apart and cleaned?
When condenser tubes have hard lime or iron scale they may be cleaned with an acid solution .
