In some areas in the north, the temperature is very low. The low temperature air energy heat pump water heater of minus 15°C can no longer meet the requirements of these areas. They need products that can still operate normally at lower temperatures.

The core technology of ultra-low temperature air energy heat pump water heater:

1. Refrigerant (refrigerant):

Refrigerant, in extremely cold environment, its heating efficiency and energy saving efficiency are much higher than that of ordinary air energy equipment.

2. Too cold defrosting:

The refrigerant from the condenser is subcooled and throttled, and then enters the evaporator to melt the frost layer on the evaporator. Compared with the commonly used reverse cycle snow melting, there is a fundamental difference.

①Defrost while heating normally, without affecting heating and indoor load

②It can better adapt to the defrosting requirements of the fin heat exchanger in different environments and different parts, and achieve point-to-point precise defrosting

③Defrosting does not require any other energy, and the heating efficiency is constant and constant

④Set in the light frost, then the frost will be removed, so that the unit can run in a frost-free state

3. Single chip micro-control system:

The control system is meticulous in logic control, small in size, light in weight, and strong in stability, and can cope with various operating conditions and protective measures.

4. EVI jet enthalpy increase:

EVI jet enthalpy technology, bipolar compression, improve heating efficiency, and can operate even under minus 25℃

5. Double-layer gold aluminum fins:

Precious metal nano double-layer coating makes defrosting faster. Effectively improve the evaporation efficiency of air and rain water, dust is not easy to accumulate, and can ensure heat exchange at minus 25°C.

6. Triple sound insulation:

The whole equipment adopts triple sound insulation cotton, combined with special shock-absorbing pads, equipment base stations and customized fans, which can reduce the noise caused by operating vibration to below 55 decibels. At the same time, it can effectively prevent the host from contacting the outside low-temperature air, and protect the stable operation of the unit in a low-temperature environment.

7.360° frost-free operation:

The chassis melting and heating technology is adopted to completely remove the accumulation of frost, snow and ice in important parts of the equipment, and truly realize 360° frost-free operation.
