A/C SYSTEM FOR HEATING AND COOLING THE WATER

A/C SYSTEM FOR HEATING AND COOLING THE WATER

In this Blog we will discuss and design A/C system that perform to cool the water and also be able to heat the water as we required. This project is designed with modern technology, system and suitability for human comfort.

Objective

Objectives of this post are mentioned as following
  1. To be able to cold the water as per human comfort in summer
  2. To be able to heat the water in winter as per requirement
  3. Operation of compressor should be in remote or in auto mode

Basic components of system

There are following basic components of our project in order to achieve our goal,
  1. Compressor
  2. Heat exchanger
  3. Refrigerant media
  4. Thermostat
  5. Blower/fan
  6. Pump
  7. Valves

Problems identification

Operation of compressor should be in remote or in auto mode.
System should be designed to heat and cold the water as per requirement of client
Required temperature not achieved.

Solution

We have added some additional technique to promote our value and to meet the customer need.
  • Thermostat is provided to provide compressor operation in auto.
  • 3 nos. of blowers or fans are used to meet the customer need for achieving required temperature.
  • 3 way vales are also utilized to meet the requirement of securing water cold or hot as per customer need.
We have provided plate type of heat exchanger instead of shell tube type of heat exchanger for better effectiveness of system.

Layout of system


As mentioned above 3 fans are used to circulate the air , 3 way valve is used to transport in three direction, Thermostat is provided to turn on and off in auto mode for operation of compressor ,heat exchanger is provided to transfer the heat and pump is provided to circulate the water.
