WITHI was theres of operation, intelligent control; innovatively designed multi-energy heat exchanger; -35°C efficient heating.

Photovoltaic energy storage heat pump:

Photovoltaic energy storage heat pump heating integrated machine, using photovoltaic electricity off-grid direct drive heat pump unit operation, according to the heat pump 24-hour power consumption configuration of the number of photovoltaic panels installed, power generation to meet the heat pump power consumption, matching a battery that uses about 16 hours of battery power. Power generation during the day, while supplying power to the heat pump to charge the storage battery, the night storage battery discharge for heat pump use, when the PV power generation can not meet, automatically switch to the national grid power supply, the working principle as shown in the diagram.

Product Features:

1. Achieve zero cost of hot water, photovoltaic heat pump is 80% more energy efficient than air energy heat pumps.

2. Remote intelligent control enables cloud operation.

3. No need to frost, no worry about low temperature and humid climate. The outdoor heat exchanger and piping of PV heat pump are circulated with superconducting liquid, which will not freeze above -45C, so there is no need for defrosting at low temperature, no freezing safety hazard, ensuring continuous heating, and higher overall energy efficiency.

4.-35℃to 48℃ wide operating range, ensuring stable temperature output in winter.

5. Innovative design of multi-energy heat exchanger. After years of field testing, design and manufacture of unique N-shaped structure of the multi-energy heat exchanger fins, to strengthen the heat absorption at the same time, to extend the applicable life, no fear of harsh outdoor environments, maintenance is more convenient.

6. Low noise fan, closed space sound insulation.

7. Widely used in hotels, factories, schools and other commercial hot water.

1. Nominal heating operating conditions: ambient dry bulb 20°C/wet bulb 15°C, initial water 15°C, and final water 55°C.

2. Models, specifications and features may change as product improvements are made. Please refer to the product nameplate for specific parameters.

After years of field testing, a special R-shape multi-energy heat exchanger is designed and manufactured, which enhances heat absorption capacity and extends its service life, making it resistant to harsh outdoor environments and easier to maintain.
