Scope of use

Air source heat pump combined supply system  

Product certification

The product meets the requirements of TUVCEEMCRoHSREACHEEI≤0.23-part3 certification

Advantage

Easy installation and operation

Equipped with Self Adapting mode AUTO (default setting), pump runs once the power is connected and adapts its performance according to actual system needs.

Control is effected by digital pulse-width modulation (PWM) low-voltage signal, enabling the pump to be used to meet different flow requirement in various systems.

Low noise and high comfort

Noise index: ≤42dB(A)

Low energy consumption

Lowest power consumption up to 6W

Multiple protection

With over-voltage and over-current protection

Eco-Design Benchmark

EEI≤0.20-Part 3

Quick release power plug

Start-up and stop the pump quickly.

 Media requirements

Medium: water or water + glycol (≤ 50%)mixture

Medium temperature : 2℃∼95℃

PH value of medium 6.5-8.5

Medium hardness 25°dH

Content of solid impurities in medium: diameter and length direction of solid impurities ≤ 0.1mm, and volume ratio ≤ 0.1%

 

Service environment requirements

The working environment temperature of the pump should be synchronized with themedium temperature of 2~95℃, as shown in the figure on the right (the maximum ethylene glycol concentration is 50%, that is, the medium The minimum temperature is -30℃)

Start and stop of pump

Starting time: the starting time of the water pump is less than 8S, the timefrom power on to reaching the maximum speed

In PWM mode, when starting from the stop state of the water pump (without powersupply), 90% of the maximum speed must be reached in at least 8 seconds

In PWM mode, start from standby mode and reach 90% of the maximum speed inat least 8 seconds

Shutdown time: the shutdown time of the water pump is less than 1 s, that is,the time from power failure to shutdown of the water pump

Performance curve

This performance curve is suitable for normal temperature water, such as pump fornon-water medium, the hydraulic performance of the pump will be reduced , therefore ,in the selection of pump, must consider the characteristics of the liquid medium

Power connection

Voltage220-240V AC(±10% )

Frequency50/60Hz

PWM input signal voltage4-24V

minimum input current4mA

PWM input signal frequency: 100-2000Hz

PWM output signal: collector open-drain output, must be connected to a pull-up resistor,the voltage is selected according to the signal acquisition range of the host computer
