What is a Heat Pump central water heater?

Heat Pump central water heater is the short name for heat pump or central hot water system. This is considered the leading green, energy-saving and safe technology solution today.

Simply put, the Heat Pump operates based on the principle of thermodynamics, similar to air conditioners. The machine will take heat from the surrounding environment (such as air, soil or water) and then convert it into heat energy to heat the water.

Therefore, the Heat Pump system is completely sealed, ensuring safety and energy saving, completely different from water heaters that use direct electricity. In addition, the Heat Pump is also equipped with an intelligent control system that helps you create hot water according to the temperature requirements and time frame of use.

Structure of central water heater - heat pump

Depending on the Heat Pump water heater line, the structure of the components will be different. However, basically, this central hot water system will include the following components:

• The heat exchanger (or condenser) is responsible for absorbing heat from the surrounding environment to convert it into thermal energy. In which, the heat exchanger has a shell made of electrostatically painted steel, while the double heat exchanger is coated with a layer of anti-corrosion and anti-rust even in salty and highly acidic environments.
• High-efficiency compressors from leading brands.
• The heat exchanger is responsible for exchanging heat between the gas and water, controlling the water temperature according to the correct settings in the machine.
• The expansion valve is responsible for regulating the solvent flow from a place with high pressure and temperature to a place with lower pressure and temperature. These valves operate very precisely, open and close quickly and have high mechanical strength, are especially safe, and do not cause danger when used.
• The central circuit board has many mode settings for easy operation. Users can set automatic and semi-automatic, or can set the time frame, temperature range according to user needs. In addition to the main parts above, the Heat Pump hot water heat pump is also made up of a number of other parts such as protective layer, cooling fan, gas copper pipe, insulation tank, auxiliary resistor...

Working principle of Heat Pump central hot water system

Heat Pump central hot water system operates on the principle of thermodynamics with the following 4 main stages:

• Evaporation phase: The heat carrier (liquid) absorbs the ambient air temperature and heats up, evaporates to form a warm heat carrier (gas). At this time, the air loses heat and condenses into water on the heat exchanger.
• Compression phase: According to the cycle, the heat carrier continues to enter the compressor of the hot water heat pump system. With its characteristic physical properties, the temperature of the heat carrier easily increases when a compressor force is applied to it.
• Condensation phase: When leaving the compressor, the average temperature of the heat carrier is very high, about more than 100 degrees Celsius. At this time, the heat carrier will enter the condenser to transfer heat to the water, gradually heating the water as required (about 60 degrees Celsius).
• Pressure reduction phase: After transferring heat to the water, the heat carrier will lose heat, become a warm heat carrier, and then continue to go through the throttle valve (pressure reducing valve) to lower it to the original temperature. From there, a completely new cycle is formed.
• Using a Heat Pump, you will overcome the disadvantages of two popular product lines today: water heaters and solar water heaters. Because with water heaters, not to mention the dangers when using (such as explosions, electric shock), you also have to wait for hot water, causing fatigue and discomfort. As for solar energy, on cloudy, rainy, stormy days, you will almost have no hot water to use.
