Structure and operating principle of heat pump

The heat pump het pump for hot water is a type of central water heater that operates on the same principle as an air conditioner. It takes heat from the air and exchanges it into hot water through a circulation pump. Therefore, it is also called an air source heat pump. The machine operates on electricity with a capacity of 0.8 KW to heat 100 liters of hot water at 60 degrees Celsius - more efficient and safer than a conventional direct resistance electric water heater.

Construction of monolithic heat pump

High pressure resistance and heat preservation for 72 hours (with a loss equivalent to 10-15 degrees Celsius).
The inner layer of the water tank is made of antibacterial enameled steel and retains heat well
The middle layer of heat preservation is thicker to ensure good and longer heat preservation
The outer layer of powder-coated steel is safe and can withstand outdoor weather and is safe.
Panasonic compressor is durable and runs smoothly
R134A or R417A gas heats with high efficiency and is environmentally friendly.
Wilo circulation pump is highly durable and can withstand temperatures of 90 degrees Celsius, runs smoothly and durably
LCD controller
The heat exchanger is coated with a protective layer to prevent corrosion from salty seawater and acid environments and prevent rust
There is a backup resistor mode (periodically disinfects the pipeline system and water tank)
Automatically defrosts in environments with freezing temperatures.

How heat pump works

Heat pump heat pump is also known as "central water heater" is a machine that uses the thermodynamic principle of 4 cycles:

- Evaporation stage (the heat carrier absorbs the ambient air temperature and heats up to evaporate into a warm gaseous heat carrier, the air loses heat and condenses into water on the evaporator.

- Compressor heats up the heat carrier, the heat carrier increases rapidly when a compressor force is applied to it.

- Condensation stage (the heat carrier when leaving the compressor is heated up to 100 degrees Celsius, enters the condenser, where it transfers heat to the water to heat up to the required temperature of 55 to 65 degrees Celsius, and is led to the insulation tank to keep the heat

- Throttle valve (after the heat carrier transfers heat to the hot water, it continues to pass through the throttle valve to form a closed loop.

Therefore, the heat pump water heater is the optimal solution to save energy for the hot water needs of families or production facilities in hot and humid climates, such as Vietnam.
