An Inverter Testing System For Computer Room Air Conditioning

In this paper, we realized the functional requirements of CRAC (Computer Room Air Conditioner) inverter test system, realized hardware platform design of test system, at the same time completed software function design and programming algorithm. For example, with our own 10KW inverter and the Schneider ATV31H 2KW inverter, we examine the output three-phase voltage and three-phase current for balance analysis and harmonic calculation. A practical application showed that the system was able to achieve an efficient automated test process and the measurements of manual measurements were the same.

A compact split system usually supplies air conditioning and hot air to one or more rooms in a building. A multi-zone system is a common use of a ductless system, and it can tune up to eight rooms (areas) from one outdoor unit. The multi-zone system usually offers various indoor unit types such as wall-mounted type, ceiling type, ceiling-embedded type, horizontal duct type, etc. Small split systems are usually cooled to a temperature of 9,000 to 36,000 Btu (9,500 to 38,000 kJ) per hour. Multi-zone system for long cooling and heating up to 60,000 Btu

In this paper, we realized the functional requirements of CRAC (Computer Room Air Conditioner) inverter test system, realized hardware platform design of test system, at the same time completed software function design and programming algorithm. For example, for our own 10KW inverter and Schneider ATV31H 2.2KW inverter, we examine the output three-phase voltage and three-phase current for balance analysis and harmonic calculation. - ... In addition to connecting to the memory device, the SOC also provides a segment-specific or application-specific interface. Examples of integrated devices are general purpose input / output pins such as Ethernet, USB, PCIe, serial port, I 2 C, extended parallel bus, and integrated display controller interface. Many of these devices are connected to non-volatile memory via native bus interface types such as serial peripheral interconnect (SPI) and NOR flash.
