The market analysis of ordinary and Detian air source water heater

 1, “Three high” problems. Air source heat pump water heater is a high automatic machine as the "human being ", judge one people whether physical health and longevity, we should check whether this people’svarious parts of his body is in working normally. There are three phenomena were high (high blood pressure, high blood glucose, high blood fats), air source heat pump water heaters also have the "three high" phenomenon (high exhaust tempertature, high pressure, high running current). If a machine a long period of "three high" operation is bound to affect the running machine operation and longevity.

1.76KW water heater operation parameters of the thermal cycling machine table (heating cycle from 40 degrees to 55 degrees machine operating parameters values)

	Normal value	Detian air source water heater	Ordinary air source water heater
Exhaust	90-95 degrees	85 degrees	100 degrees (exhaust lead to abnormal failure easily)
Pressure	1.8-2.5MPA	2.2MPA	2.7MPA (lead to abnormal high pressure fault easily)
Running current	8A	8A	8.8 ~ 9A (the current exceeds the rated current show that the compressor work overload, damage the compressor logevity)

2, The low utilization ratio of hot water in tank

Ordinary air source heat pump water heater storage tank, supply hot water depends on water pressure , that is, the cool water coming into while the hot water forced to come out of the water tank , so cold water will mixed with hot water at the same time filling into the water tank, thermal efficiency is very low. Hot water utilization ratio less than 50%.

Detian R & D team take the above problems as a research subject, it took nearly three months to finally solved this problem, developed a new thermal storage tank, and obtained national patent. The new patented water tank, separated the hot water and cool water successfully through a special design, solved the mixing problem, making the water utilization rate up to 80-90%.

3, Severe frosting in winter, heating capacity is very low, can not guarantee regular supply of hot water.

Ordinary air source heat pump water heater does not fundamentally solve the frost problem, their solution is to stop heating water, converting the refrigerant flow direction, with 5-10 minutes will stay in the frost on the evaporator block melt away.

Detian air source water heater technology R & D team developed the anti-frost evaporator  which solved this serious problem. Assure user have enough hot water to use, the machine work stablely in winter.

4, immersion copper corrosion problem of leakage fluorine

Common way is to heat the water just heat exchanger immersed in the tank directly. The heat exchanger is made of copper, copper for a long time to be immersed in the water heater where corrosion perforation over time, leakage of fluorine. Lead scrap tanks, machine paralysis.

Detian technical team invented a high efficient cellular beam tube heat exchanger. It’s main feature is large exchange area, high efficence. The heat exchange used in Detian’ls main unit which solved the long-term immersion in water, copper pipe corrosion problems, could heat water normally below10 degrees.http://www.fsdetn.com/

Ordinary air source heat pump water heater due to technical constraints, can not solve the three-high problem, Detian technical experts breakthrough technology limitations, has been completely solved the"three high" problem. How to cycle In the high-temperature: want to know more, please call us.
