Description

Tongyi  Double Wall air source heat pump is the best choice for hot water supply of commercial projects, such as hotels, schools, and other large buildings, which need large water volume supply. The circulating heat pump is connected to the water tank with a separate water pump, it will supply hot water and store it in the water tank but not directly to end facilities in case of different water demands.

Capacity Range:

5KW, 10KW,20KW,40KW,80KW

Key Features 

Copeland scroll compressor

World-famous scroll compressor with low energy consumption and high energy efficiency output, which effectively shortens the heating water time and double extends the useful life of the unit. Tongyi heat pump can increase over 20% heating capacity even though it works under severe weather.

Multi-protections

The system runs safely, steadily, and reliably thanks to our full protection: high-temperature protection, compressor overload & overheat protection, power phase sequence & over/under voltage protection, etc.

Multi-protections

EEV, precise flow control

Wide working temperature range, faster and more accurate refrigerant flow control than capillary and mechanical expansion valve. Best choice to achieve higher efficiency and energy-saving.

EEV, precise flow control

Auto-defrosting program and anti-freeze

Intelligent defrosting technology, which can determine the time of defrosting according to the operating conditions of the unit (running time, exhaust temperature), ambient temperature, and thickness of frost, so as to achieve intelligent defrosting when it is necessary, which greatly shortens the defrosting time by more than 20% and ensures the high heating capacity.

Auto-defrosting program and anti-freeze

Flexible Installation

The Cuboid shape module design of the unit makes the project installation save more space.

pannel control

Remote control

BMS contact point / Modbus support(with RS485) to Amazon cloud, realize remote control function optional

 

IoT

With IoT technology, we can check the heat pump status remotely. When there is fault occurs, it is easy for us to check the product information and give immediate support to our customers.

With OTA(update over air) technology, If there is an error that happens on the software, we can do the remote service by updating the software online. And when the software has a new version with the function upgraded, as long as we got your permission, we can update the software remotely.
