According to the market survey from Juteng, China's leading brand of air source heat pump, a device to meet requirement of both "heating in winter & cooling in summer " , many interviewees choose air source heat pump with heating & cooling, rather than traditional central air conditioning.
How did air-source heat pump with heating & cooling catch up and be widely accepted by consumers?
A view from the professor of Guangdong Juteng Environmental Protection Equipment co.,ltd.that although the central air conditioning and air source heat pump with heating & cooling can meet both requirement,there is some clear differences between them.
Central air conditioning is derived from refrigeration demand, initially as single-cooling function, later began to have heating function. However, the main direction is cooling, the unit in the low temperature has poor performance. In most cases, the central air-conditioning unit works with electric heating in winder, the energy consumption is larger in heating mode.The heating testing standard is 7°C, working temperature range is over 0°C.
In general, the technical difficulty of refrigeration equipment is relatively small, while heating is relatively difficult. Air source heat pump started from heating function, later development with cooling function. After the technical development in recent years, air source heat pump reaches low temperature of -30°C.
In design standard, Juteng air source heat pump is also much higher than traditional central air conditioning. Take the unit as example, the central air conditioning uses single-cooling compressor, but air source heat pump aims to meet the heating requirements under low working temperature, it must be designed with a higher standard compressor; the fin space is 15% more than that of traditional central air conditioning, to ensure more effective cooling and heating. Air source heat pump consists of four key components (compressor, condenser, throttle parts, evaporator),same as central air conditioning, it has EVI compressor for low temperature model, enable air source heat pump to work regularly with efficiency and stability in -30°C.
In addition, Air-source heat pumps can also be combined with various forms, like floor-heating, fan coil and radiator, to provide more comfortable heating effects and diversified choices for users.
The introduction from Juteng has that in the operation of the unit, because air source heat pump only needs to use electricity to drive the compressor to the refrigerant work, and make heat exchange through the heat exchanger. In the entire heating operation process, energy consumption is only about 1/3 to 1/4 of the traditional electric equipment.The user just switches the mode to have cool function, the operation is very convenient.
