Two or three years ago, most people do not know about air source heat pump products. They may know more about air source heat pump water heater. Then what are the differences between ultra-low ambient temp heat pump and regular air source heat pump?
A. The measuring condition is different
The principle of air source heat pump is absorbing in the air, then convert into high heat energy through the work of the compressor. After exchange with water system to provide hto water, heating, cooling, drying or other purposes.
Regular air source heat pump can keep working at -10 deg c. If lower than -10 deg c ambient temp, it may appear the following problems:
1. The compressor will be easy to have problems
2. The unit will be hard to defrost
B. Different Technologies Involved
•Operation technology
Due air source heat pump host is usually installed outdoor, it could easily to get forsting under rain and snow weather.
However, ultra-low ambient temperature air source heat pump host can intelligently judge the defrosting demand. According to the operation status of the unit (running time, exhaust temperature, etc.), ambient temperature, frosting thickness, intelligently judge whether start to defrosting. Greatly prolonging the defrosting cycle, shortening the defrosting time by 20%, ensuring the efficient operation of the heat pump unit.
•Enthalph enhancement technology of jet
Because the heating efficiency of air source heat pump will be greatly reduced in extremely cold weather, those will not fulfill the floor heating demand. Ultra-low ambient temperautre air source heat pump uses jet enthalph enhancement technology to create a secondary suction port in the scroll. Through the second suction loop, the refrigerant flow rate will be increased. Also the refrigerant circulation capacity of the unit will be increased. The refrigerant circulation system will be greatly enhanced by 10% higher thatn that of the general unit as well. Make full use of the refrigerant flow rate and utilization rate in compressor to improve the stability of system operation and heating efficiency.
