EVI ON/OFF type Air source heat pump water heater(For Hot Water only)

Features:

Panasonic compressor

"Small Size" "big horsepower"!

Relying on the mature technology of B series. More optimized motor design. Excellent vibration and noise characteristics.

High reliability bearings, increased oil pool volume.

Modular rotation work

According to the load conditions of the system, the unit rotates the module units that are turned on first, and distributes the running time of each module unit in a balanced manner, which greatly improves the reliability and service life of the unit.

Intelligent defrosting technology to reduce heating attenuation

Air-cooled heat pump units are prone to frosting when the air density is low and the humidity is high. The air-cooled heat pump module unit can accurately judge the defrosting timing according to the main parameters of the heating operation and the load change, so as to achieve defrosting with frost and normal heating without frost, and can perform forced manual defrosting according to the actual situation .

Modular design, more flexible installation

Unit modules of different capacity specifications can be freely combined, and a maximum of 16 units can be connected in parallel, with strong compatibility and scalability. According to the site characteristics of the installation site, the user can choose a variety of combination connection methods to realize the parallel use of 1-16 modules, and the maximum cooling capacity is as high as 2080kW, fully meeting different needs. The air-cooled module units of the same system are started in stages and run in a balanced manner, reducing the impact of the starting current of the units on the power grid.

Building intelligent control to improve management reliability

Modbus is an open protocol that is widely used, especially in BMS building control systems. The unit can be connected to the BMS system through the Modbus protocol to realize remote control of multiple air cooling and heat pump modules.

Equipped with EVI technology, stable operation at ambient temperature -30°C, Wide running range, from -30℃ to 43℃.

Water side heat exchanger

High-efficiency shell & coil heat exchanger with both cooling and heating is adopted, with water in the tube and fluorine outside the tube. High heat exchange efficiency, small size, excellent water quality, strong antifreeze ability, stable and reliable

Internally threaded copper pipe

The inner threaded copper tube is adopted, and its inner surface is designed with grooves, so that the contact area with the refrigerant is larger, the heat exchange is more sufficient, and the heat exchange effect is better.

High precision electronic expansion valve

Electronic expansion valves are selected as the refrigerant flow control components to maximize performance and minimize defrost effects. The maximum 3000-level EXV adjustment can control the refrigerant flow stably and precisely. The response speed is fast, which can realize light-load startup, reduce heat loss during shutdown, and improve unit reliability.

Fan, motor

Large air volume, low noise blades; High torque, high efficiency motor.

High efficiency and low noise.

Reservoir

Large liquid receiver is used to store the condensed liquid refrigerant to prevent the liquid refrigerant from affecting the heat exchange of the heat exchanger, reduce the system pressure, and ensure more reliable system operation.
