Product introduction

Core comparison of VVVLCAHP and common air source heat pump:

Variable Frequency Ultra-Low Temperature Heat Pump

Ordinary air source heat pump

Operation range of heating:-35℃~20℃
Operation range of refrigeration:21℃~43℃

Operation range of heating:-25℃~25℃
Operation range of refrigeration:a21℃~43℃

Ultra-high effluent temperature and effluent temperature as high as 65 C are suitable for traditional heating.

The effluent temperature is 65 C, and the heating energy begins to decay at low temperature.

The energy efficiency ratio of super-high energy efficiency is 3.8 under the national standard heating condition. While ensuring the high energy efficiency of heating, the refrigeration energy efficiency of super-high energy efficiency is more than 3.1.

The energy efficiency ratio of heating condition is generally between 2.1.

One machine, two-purpose heating and cooling, can be external heater, reduce initial investment

Can not be used with external heater


What are the characteristics of VVLSHP?

1. Frequency conversion ultra-low temperature air source heat pump is more energy-saving, more than 60% energy-saving than electric heating, more than 40% energy-saving than gas.

2. Multi-machine parallel connection is standby. When a temporary failure of a machine stops, it can ensure the low-temperature operation of the system without the risk of frost cracking.

2. Frequency conversion ultra-low temperature air source heat pump has strong comfort, heating is not dry, refrigeration is not harmful (to eliminate air conditioning diseases)

3. Indoor natural media, non-toxic, harmless, radiation-free, frequency conversion ultra-low temperature air source heat pump makes home more livable

4. Frequency conversion ultra-low temperature air source heat pump adopts split structure design, which can prevent freezing more effectively. The problem of machine water pipes and plate replacement freezing cracking occurs when the temperature is lower in winter.

5. Ultra-wide heating range, frequency conversion ultra-low temperature air-source heat pump can produce heat efficiently in low temperature environment of minus 35 degrees.

6. Frequency conversion ultra-low temperature air source heat pump has flexible heating time and free control of heating temperature.

7. Inverter Ultra-low Temperature Air Source Heat Pump has a long design life and a long life of 15-20 years.

8. Frequency conversion ultra-low temperature air source heat pump has high safety, water and electricity separation, no combustion, so that the home is safer.

Frequency conversion ultra-low temperature air source heat pump is a kind of high-tech hot water equipment with high efficiency, energy saving, safety and environmental protection. It solves the technical bottleneck of poor stability, frosting, insufficient heat production and large power consumption of ordinary air in cold environment. Frequency conversion ultra-low temperature air source heat pump provides comfortable heating environment and summer system for extremely cold areas. Cold and make domestic hot water for use.
