The working process of the heat pump water heater is that after the compressor compresses the low-pressure refrigerant flowing back, it becomes a high-temperature high-pressure gas discharge, and the high-temperature high-pressure refrigerant gas flows through the copper pipe wound around the water tank, and the heat is conducted to the water tank through the copper pipe, and is cooled down. The refrigerant becomes liquid under the continuous action of the pressure, and enters the evaporator after the expansion valve. Since the pressure of the evaporator suddenly decreases, the liquid refrigerant rapidly evaporates into a gaseous state and absorbs a large amount of heat. At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, and the energy in the air is absorbed by the evaporator, and the temperature of the air is rapidly lowered to become cold air. The refrigerant that has absorbed a certain amount of energy is then returned to the compressor for the next cycle.
The air source heat pump water heater can absorb the low temperature heat energy in the air and convert it into high temperature heat energy inside the machine, and then heat the water temperature. The air source heat pump water heater is very energy-saving and the efficiency is also very high.
The air source heat pump is one of the most advanced energy utilization products in the world today. With the rapid development of the economy and the improvement of people's living standards, domestic hot water has become a necessity for people's daily life. However, traditional water heaters (electric water heaters, fuel oil and gas water heaters) have disadvantages such as high energy consumption, high cost and serious pollution; The operation of energy-saving and environment-friendly solar water heaters is subject to meteorological conditions. The heating principle of the air source heat pump is completely different from that of the traditional solar water heater. The air source heat pump uses air, water, solar energy, etc. as the low temperature heat source, and the air source heat pump uses the electric energy as the power to extract heat from the low temperature side to heat the domestic water, and the hot water passes through the circulation. The system feeds directly to the user as a hot water supply or uses a fan coil for small area heating. Air source heat pump is the best solution for large, medium and small hot water centralized supply systems in school dormitory, hotel, bathing center and other places.

Meniscus lenses are divided into positive meniscus and negative meniscus lenses. A meniscus lens has one side of the lens that is convex and one side that is concave. It can be a converging lens or a diverging lens, determined by the refractive index, curvature and radius together. Widely used in photographic systems, projection systems, imaging systems, optical viewfinders, and laser measurement systems.
