Guangzhou Public Security and Fire Systems Engineering Squadron hot water applications (Figure) – air to water heaters, energy saving – heat pump industry
Program description and evaluation: As Guangzhou Public Security and Fire Squadron Bathroom in the dormitory on both sides, the roof center towers separated by floor, and the floor is relatively long, construction difficult. Because your organization is a special unit, hot water requirements in the relatively higher, and recommended the program, the program has produced enough water, water short, traffic, open 24 hours a day have enough hot water faucet features.

Patent description Pump heart??? 9 Hang patent "shell and tube heat exchanger (commonly known as blisters)" Technical Note:
Patent No.: 200820042929.0 Figure 1: "bubble" diagram looks
Technical note: 1, "bubble" inside the ring structure, similar to case selection and liquefied gas cylinders, the internal structure shown in Figure 2, the inlet connected to the outer ring, return air inlet connected to the inner ring, 2mm thickness of the outer wings with internal thread , diameter 19mm (maximum diameter market can sell) as a precision brass pipes, which are out of the water pipe diameter 19mm;
2, the heat principle is: to heat the refrigerant gas by the compressor acting from the inlet into the heat exchanger ("blister"), cold water from the inlet into the heat exchanger ("blister"), heat exchange with each other After low-temperature liquid refrigerant to form into the inner ring, flows back from the back to the compressor air intake, cold water into hot water, heat from the outlet back to storage tanks, and so repeatedly, until the set temperature value, the host to stop working.
3, now widely used aircraft market works "tube type" heat exchanger (household machines generally use the "coil" heat exchanger), which cover a large number of small copper pipe in hot-media exchange (console directly placed in the tank to heat exchanger coil), the thermal efficiency of the heat exchanger tube heat exchanger depends on the length of the longer length, the higher the efficiency, small disadvantage is that heat exchanger copper and copper thin wall tube (usually only 0.4mm), long-term immersion in water for heat exchange, prone to scale adhesion of copper to wall perforation, leading to the compressor inlet, compressor, heat exchanger, scrapped;
4, "nine permanent" company whose core troops from the "cooling of the Kingdom," Kelon Group Kelon's fine heritage of ideas and technology, daring use of central air conditioning heat exchanger of the "bubble" to pump heat exchange, due to "bubble" technology has central air conditioning industry in the long-term, heavy use, has stood the efficient use of time and the use of the dual test, so "9 Hang" with its unique patent "shell and tube (commonly known as blister)" "dynamic heat exchange "Technology, solve the common heat pump water heater copper pipe corrosion risks, greatly increased the heat pump's efficiency and service life;
Technical Data 1, engineering and technical parameters
1) heat pump water heaters energy efficiency ratio (to SKR-100 as an example)
1.1) EER curve: EER curve
Power consumption
1.2) heat pump hot water unit corresponding ambient temperature of the EER
