7.7kw~12.8kw DC inverter units for heating cooling hot water
1. DC Inverter Air to Water Heat Pump adopt DC Inverter compressor,
DC Inverter motor,When the system start,the compressor is running rapidly to make the room temperature reach the setting temperature,When the room reach its setting temperature,the system will keep its setting temperature effectively and accurately by controlling the compressor and motor's running speed,no need use more electricity.
2.DC Inverter technique achieve the machine's big power and high energy efficiency rate,COP 30% Higher than Normal heat pump,It has features of good running economy and work stability.
3. Designed as Monobloc Type, can be Connected by Copper pipe, Installation With Simple, Flexible and Conveniently, The Indoor Unit can be Installed in Kitchen, Bathroom or basement, Ensuring less Energy loss, Also Prevent Water Pipes From Freezing in Cold Winter and sun Exposure in hot Summer.
6. Using and MITSUBISHI Rotary Twin-Cylinder DC Inverter Compressor and HITACHI DC Inverter EVI System Scroll Compressor, Green Environment, High-Efficiency,Providing Wonderful Performance and Reliability.
How Do Inverter Heat Pumps Work?
In a standard heat pump or air conditioner, a fixed-speed compressor comes on at full capacity to meet the indoor temperature requirement and then turns off once the target temperature is met. This results in peaks and valleys in both power consumption as well as inside temperature.
The inverter, or VFD, uses a rectifier to convert the incoming alternating current (ac) to direct current (dc), then uses pulse-width modulation in an electrical inverter to produce ac of a desired frequency. The variable-frequency ac drives a brushless motor, or an induction motor, as the speed of an induction motor is proportional to the frequency of the ac. The compressor can then run at different speeds
