A heat pump water heater is an efficient heat energy enhancement and transfer device based on the reverse Carnot cycle. It uses a small amount of electrical energy as power and a refrigerant as a carrier to continuously absorb low-grade heat energy from the air, convert it into usable high-grade heat energy, and then release the high-grade heat energy into the water that needs to be heated to produce domestic hot water, which is then transported to users through hot water pipelines. It can transfer the heat from low-temperature heat sources (such as air, soil, seawater, groundwater, etc.) to the water that needs to be heated, achieving the heating function of water
Working principle
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
