Split-system ACs have an outdoor compressor and an indoor evaporator. Refrigerant moves between them to cool your space.
Split system air conditioners are the most popular type of AC system in many homes and businesses. They offer a superior level of cooling performance compared to older window unit systems. Unlike window units, split systems separate the compressor and condenser (located outdoors) from the evaporator (located indoors). This design results in significant noise reduction and increased energy efficiency. The outdoor unit houses the components that generate noise and heat, which are kept outside of the living area. The indoor unit is responsible for delivering cool, conditioned air.
The system operates using a refrigeration cycle. The compressor compresses refrigerant, raising its temperature and pressure. This heated refrigerant is then passed through the condenser, releasing heat to the outside air. The cooled, lower-pressure refrigerant then flows through the expansion valve into the evaporator. Within the evaporator, the refrigerant absorbs heat from the indoor air, cooling it. This cooled air is then circulated throughout the room using a fan. A thermostat controls the entire system, maintaining the desired temperature. A variety of indoor unit styles are available to complement different room aesthetics and installation needs.
Selecting the right split system requires consideration of factors like room size, cooling capacity, energy efficiency rating (SEER), and features. Consulting with a qualified HVAC professional is highly recommended to ensure you choose the correct size and model for your specific needs.

Detailed Explanation:
SharedPreferences in Android is a way to store key-value pairs of primitive data types. It's ideal for saving small amounts of data, like user preferences or settings. Here's a breakdown of how to use it:
Obtain SharedPreferences Object:
SharedPreferences sharedPref = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
getSharedPreferences() retrieves the SharedPreferences object. The first argument is the name of the preference file (a string). Context.MODE_PRIVATE makes the file private to your application.Editor Object for Modification:
SharedPreferences.Editor editor = sharedPref.edit();
Editor object is needed to make changes to the SharedPreferences.Storing Data:
editor.putString("username", "john_doe");
editor.putInt("user_id", 12345);
editor.putBoolean("loggedIn", true);
editor.putFloat("user_score", 98.5f);
editor.putLong("timestamp", System.currentTimeMillis());
put methods based on the data type. You can chain multiple put calls.Applying Changes:
editor.apply(); // or editor.commit();
apply() asynchronously commits changes, while commit() does it synchronously. apply() is generally preferred for better performance.Retrieving Data:
String username = sharedPref.getString("username", ""); // Default value is empty string
int userId = sharedPref.getInt("user_id", 0); // Default value is 0
boolean loggedIn = sharedPref.getBoolean("loggedIn", false); // Default value is false
float userScore = sharedPref.getFloat("user_score", 0.0f); // Default value is 0.0f
long timestamp = sharedPref.getLong("timestamp", 0L); // Default value is 0L
Example: Saving and Loading a User's Name
SharedPreferences sharedPref = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putString("userName", "Jane Doe");
editor.apply();
String userName = sharedPref.getString("userName", "");
// userName will now contain "Jane Doe"
Simple Explanation:
SharedPreferences lets you save simple data like user settings easily. Get a SharedPreferences object, use an editor to add/change values (using putString, putInt, etc.), then apply or commit the changes. Retrieve values later using getString, getInt, etc., and provide default values.
