- Q1. Study fundamental concepts of Refrigeration.
- Q2. Explain Refrigeration cycle
- Ans.
Refrigeration cycle is a process of removing heat from a low-temperature reservoir and transferring it to a high-temperature reservoir.
The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.
The refrigerant is compressed by the compressor and then condensed in the condenser, releasing heat.
The high-pressure refrigerant then passes through the expansion valve, where it expands ...
- Q3. Condenser working principal
- Ans.
Condenser is a device that converts refrigerant vapor into liquid by removing heat from it.
Condenser receives high-pressure, high-temperature refrigerant vapor from the compressor.
Heat is removed from the refrigerant vapor by either air or water.
As the refrigerant vapor loses heat, it condenses into a high-pressure liquid.
The liquid refrigerant then flows to the expansion valve or metering device.
Examples of condensers...
- Q4. Explain about evaporator
- Ans.
An evaporator is a heat transfer device that converts a liquid into a vapor or gas.
It is used in refrigeration systems to absorb heat from the surrounding environment.
The liquid refrigerant is evaporated inside the evaporator coil, which causes it to absorb heat from the air or water passing over the coil.
The evaporator coil is typically made of copper or aluminum and is filled with refrigerant.
The refrigerant evaporat...
- Q5. Explain about subcoolers and why it is required
- Ans.
Subcoolers are used in refrigeration systems to cool the refrigerant below its saturation temperature.
Subcoolers remove any remaining heat from the refrigerant after it has been condensed.
This ensures that the refrigerant is in a liquid state before entering the expansion valve.
Subcoolers improve the efficiency of the refrigeration cycle and increase the cooling capacity of the system.
Examples of subcoolers include she...
- Q6. How to control super heat
- Ans.
Superheat can be controlled by adjusting the refrigerant flow rate or by adjusting the evaporator pressure.
Adjust refrigerant flow rate
Adjust evaporator pressure
Use expansion valves to regulate refrigerant flow
Use pressure regulators to control evaporator pressure
Ensure proper insulation and airflow in the system
Regularly maintain and clean the system

- Q1. What are oops concepts in java, explain real time scenario
- Ans.
OOPs concepts in Java include inheritance, polymorphism, encapsulation, and abstraction.
Inheritance allows a subclass to inherit properties and methods from a superclass.
Polymorphism allows objects to take on multiple forms and behave differently based on their context.
Encapsulation hides the implementation details of an object and only exposes necessary information.
Abstraction allows for the creation of abstract class...
- Q2. Uses of interface, inheritance
- Ans.
Interfaces define contracts for behavior, while inheritance allows for code reuse and polymorphism.
Interfaces allow for loose coupling and abstraction, enabling multiple implementations of the same behavior.
Inheritance allows for code reuse and extension of existing classes, reducing code duplication.
Polymorphism allows objects of different classes to be treated as if they were of the same class, simplifying code and i
- Q3. SQL query for join of tables
- Ans.
SQL query for joining tables
Use JOIN keyword to combine two or more tables based on a related column
Specify the columns to be selected using SELECT keyword
Use ON keyword to specify the condition for joining the tables
Different types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN
- Q4. Java concepts used in your project
- Ans.
Used Java concepts such as inheritance, polymorphism, and exception handling in my project.
Implemented inheritance to create a base class and derived classes with specific functionalities.
Utilized polymorphism to allow objects of different classes to be treated as if they were of the same class.
Implemented exception handling to handle errors and prevent program crashes.

- Q5. Overloading vs overriding, practical uses
- Ans.
Overloading is having multiple methods with the same name but different parameters. Overriding is having a method in a subclass with the same name and parameters as a method in the superclass.
Overloading is used to provide different ways to call a method with different parameters
Overriding is used to provide a specific implementation of a method in a subclass
Overloading is resolved at compile-time while overriding is r...
