Shandong Ji'nan 7 years old 10 years of R & D "air conditioning water heater"
South Xirun, a large number of air-conditioned outdoor units began to breathe hot air. In an old factory building in the eastern suburb of Ji'nan, however, a modified air conditioner was shut down as long as a switch was pressed and an outdoor fan stopped, and a water storage device connected to it later released hot water. At the same time, the indoor machine was still working, and the ammeter showed a decline in electricity consumption.
"try the water temperature. Do you want it hot?" In June 19th, Xing Jinliang, full of white hair, raised his head from a pile of machine parts to ask reporters. Xing Jinliang is the inventor of this technology. He is 73 years old and graduated from Shandong Mechanical College in 1959. After retiring in 1997, he had a strong interest in the principle of steam compression heat pump for air conditioning units. In the past more than 10 years, he spent almost all his energy and financial resources. The developed "air conditioner water heater" has obtained two utility model patents and won the national invention in May this year.
Xing Jinliang told reporters that "heat pump", also known as the "thermostat", is the core component of air conditioning. No matter whether the refrigeration and heating system is a set of devices, only with different uses and different parts of utilization, the heat absorbing end of the air conditioner is connected to the indoor, absorbing indoor heat and cooling. Gao Wenduan access to the outside, will heat up after the release of high temperature heat, the formation of cold air conditioning. The reverse flow is that the outdoor becomes the endothermic low temperature end, and the indoor becomes the high temperature end of the output heat, forming the thermal air conditioner. In recent years, the heat pump water heater and the hot air conditioner on the market just used the hot end of the heat pump, which is expensive.
"air conditioner water heater" can be used in the cold and hot end of heat pump after reloading but it can do cold air conditioning, hot air conditioning and single supply of hot water alone, and use the waste heat to heat water in the cold air conditioning. Although spring and autumn do not use air conditioning, they can only provide hot water for living, which overcomes the problem of half an hour of air-conditioning. Xing Jinliang told reporters that heat pump cold and hot end two-way use, functional cost and use cost greatly reduced, air conditioning does not increase electrical power, the efficiency is increased by 5% to 10%; air conditioning water heater is equivalent to the synthesis of air conditioning and heat pump water heater. Sharing the compressor, evaporator, throttle device, machine shell, electrical circuit and so on, so the cost is greatly reduced, and the heat efficiency of the ordinary water heater is increased by two times, and more than half of the energy saving. After the successful development of
, Xing Jinliang has many links and is free to try in some barber shops and hotels. Mr. Wang, the owner of a barber shop near the Jiefang Bridge, told reporters that after reloading last year, the air conditioner kept its original performance, and a hot water heater was added, and the electricity bill could save up to ten thousand yuan a year.
