Low Temperature Dc Inverter Heat Pump EVI With Air Source Circulating

Features of Air To Water Low Ambient Temperature Heat Pump EVI Inverter Technology

.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 defrost:

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 respond to 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:

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

The three characteristics of Air To Water Low Ambient Temperature Heat Pump EVI Inverter Technology intelligent defrosting technology are as follows:

1. Quick defrost characteristics The unit can quickly defrost under severe defrost conditions (3 minutes defrost).

2. Accurate defrosting characteristics The unit accurately judges the frosting situation, the unit frost layer coverage rate is not higher than 85%, the unit does not defrost, and the unit frost layer coverage rate is higher than 85%, it can defrost by itself and defrost thorough.

3. The nominal coefficient of performance (COPh) for heating units with high energy efficiency characteristics is higher than 2.50kW/kW.
