My experience with Sunniva has been so good that I have personally recommended their products to lot of people. Their technical expertise, product quality, focus on customers’ requirements are few qualities that make them stand out from the rest.
All in One Heat Pump:
In an all-in-one heat pump water heater, the heated refrigerant is usually conveyed through a heat exchanger that’s wrapped around the outside of the tank, under the insulation. The refrigerant heats the tank by conduction, transferring heat from the condenser coil through the tank shell, to the water
inside.
Heat pump is a device in which the refrigerant R134a is continuously changing the shape from gas to liquid. It pumps out the solar energy from the air in the room and together with electrical energy consumed by compressor it gives out the total heating capacity which is accumulated in the water storage tank. Evaporator is an air-refrigerant heat exchanger. In the evaporator the refrigerant
is vaporized at low pressure and relative low temperature. Because of vaporization the heat transfer form air to refrigerant starts. Vaporized refrigerant comes in the compressor where the pressure goes higher and also the temperature. From compressor the vaporized and high temperature steam goes in the condenser (refrigerant-water) where again the heat is transferred from refrigerant to water. The refrigerant is now in liquid shape idler high pressure. After it flows thought the expansion valve it reaches the basic shape and he process goes around again. The circuit is in process until the water temperature in the water storage tank reaches the set point.
Features
High efficient Micro-Channel Heat Exchanger
Larger heat exchange area, Better heat transfer effect and More durable performance.
The energy efficiency grade of the system can reach 4.2 even above.
Not touch with water in the water tank, so the heat exchanger has no risk of corrosion, scaling, leakage, etc.
Enamel Water Tank Brings You Healthier Water Quality
High pressure and fatigue resistance which pass 280,000 times pulse test.
High corrosion resistance because enamel coating makes the welding line of steel plate separate with water, so with long working life.
♦ High Efficient Compressor
Being internationally-renowned brand dedicated compressor for heat pump, it is more reliable in system matching and quieter in operation.
♦ Intelligent Defrosting
With intelligent defrosting design, it can revolutionary solve the bottlenecks of heat exchangers in cold winter such as frosting and slow heating, etc., allowing you to spend a more comfortable winter.
♦ 1:1 Gold Ratio
The unit and water tank are matched with a gold ratio to eliminate the phenomenon of disharmony, so that it is more energy-saving and professional.
