Most of the truck air conditioners we use have a not-so-smart heart (the compressor)! The compressor is arguably the core component of the air conditioner - circulating refrigerant inside the unit. What the heart is to man, the compressor is to the air conditioner!
The compressor is the part of the air conditioner that converts the refrigerant from a gas to a liquid. It operates according to the temperature of the room: it runs at full speed when cooling is needed and stops completely when the temperature is low enough. The main function of the compressor is to compress the refrigerant inside. When the refrigerant is compressed, it is converted from a gas to a hot liquid. Then it passes through a cooling condenser where the refrigerant is cooled to a liquid and then spreads inside the cab.
So basically, a compressor is like a pump designed for steam rather than water, it compresses the warm refrigerant gas into a hot liquid and then pushes it onto the coil, releasing the heat into the environment.
Refrigerators have been around before in history, and in fact, even today, most of them are equipped with standard compressors. This standard compressor will start when the temperature in the refrigerator exceeds a certain threshold limit. But when the temperature falls below that threshold, it shuts down and waits for the next refrigeration cycle.
So basically, the standard compressor is an "on" or "off" single-speed compressor. Since it is constantly "on" and "off", it increases the wear and tear on the unit and creates noise when switching between states.
Most air conditioners start out with an unintelligent heart. It was an inverter added to the compressor, which gave intelligence to other devices such as refrigerators. Now, from a hardware and design point of view, this is achieved by using a DC DC motor. The advantage of using a DC motor is that it allows the compressor to run at different levels of intensity depending on the temperature and other environmental conditions.
Non-inverter or fixed speed air conditioners run at a fixed speed and at a fixed power. This means that the compressor must stop and start again to maintain the desired room temperature. In this type of arrangement, the compressor is either off or on. When it is on, it works at full capacity and consumes all the power. When the thermostat reaches the desired temperature setting, the compressor stops and the fan continues to run.
Inverter air conditioner technology was developed in Japan and is now used worldwide in such areas as air conditioners and refrigerators. In an inverter air conditioning system, the speed of the compressor changes to ensure energy-efficient operation and precise cooling or heating as needed. When the compressor needs more power, it delivers more power. When it requires less power, it delivers less power.
Inverter and non-inverter systems both provide similar functionality, but differ in the type of compressor motor running in the system. The compressor is responsible for compressing the refrigerant into a liquid, then shutting it off and expanding it. Inverter air conditioning units can be designed in such a way that they can save up to 30-50% on electricity consumption.
Once air conditioners are added to the list of electronic devices used in a home, the electricity bill increases significantly. While it is quite difficult to reduce the "significant" impact of air conditioning on electricity bills, a significant portion of it can be managed by choosing the right technology, optimizing use, proper installation, maintenance, operation and insulation.
