1、 Performance characteristics of semi positive displacement heat exchanger (I) HRV-01 / 02 characteristics: semi positive displacement heat exchanger is a new product of foreign similar heat exchanger with international advanced level, and its main thermal performance parameters have been tested by the national first-class thermal testing unit & mdash& mdash; The measurement of North China industrial boiler test center of the Ministry of mechanical and electrical engineering exceeds that of foreign similar equipment
Compared with the current advanced products at home and abroad, it has the following characteristics: 1
The heat exchange part is an improved fast heat exchanger with high heat transfer coefficient and large heat exchange
The heat exchange of the product with the same volume is equivalent to 5 ~ 8 times and 2 ~ 3 times of the traditional positive displacement heat exchanger and the new positive displacement heat exchanger respectively
2
The water storage part stores hot water for 10 ~ 20 minutes, and the head loss of the heated water ≤ 0
2m, so it can maintain the characteristics of stable water pressure and temperature, safety, water saving and comfortable water use under the condition of setting general automatic temperature control valve
3
All hot water is stored in the tank without stagnant water and cold water area, and the volume utilization rate is 100%
4
When the water consumption of this product is very small or no water is used, the circulating pump on the hot water pipe network can be used to maintain the water temperature in the tank, so that the heat exchange part is always in the heated water flow state during heat exchange, with sufficient heat exchange and energy saving, and the outlet temperature of heat medium is lower than 50 ℃
5
The shell of this product is made of stainless steel, carbon steel lined with copper, lined with stainless steel composite plate, and the U-shaped pipe is purple copper pipe or stainless steel pipe, which completely solves the problem of serious corrosion inside the shell and affecting the water quality
When used in practical projects, due to the steel consumption, the floor area is far lower than that of the volumetric heat exchanger, so the total cost is still lower than that of the latter
6
The tank is small in size and light in weight
The heat exchange tube bundle can be pulled out along the horizontal direction, which is convenient for installation and maintenance
（2） Dbhrv-01 / 02 performance characteristics: 1
Dbhrv-01 / 02 corrugated tube heat exchanger has other characteristics besides HRV-01 / 02 characteristics: during water water heat exchange, the outlet temperature of heat medium water t2≤ At 50 ℃, the waste heat accounting for about 17% of the total heat exchange is recovered, which is more energy-saving
2
The temperature drop of heat medium is larger, the heat exchange is more sufficient, and the heat exchange capacity (heat production water volume) is about the same type of HRV & ldquo; U-tube & rdquo; 1
5 ~ 2 times of
2、 Design instructions 1
This series of heat exchangers are applicable to the hot water supply system of general industrial and civil buildings
The heat medium is high and low temperature softened hot water or solar hot water, and the type of medium shall be indicated in the design
2
Each specification of heat exchanger is equipped with two kinds of heat exchange areas
In order to ensure the heat storage time of 10 ~ 20 minutes and give full play to its efficient heat exchange performance, both kinds of heat exchange areas can be selected for water-water heat exchange
3
The outlet temperature of heated water shall not be higher than 75 ℃
In actual use, in order to delay scaling, the outlet temperature of heated water should be controlled between 50 ~ 60 ℃
4
Material: the shell is made of stainless steel SUS321 and SUS304, carbon steel Q235-B lined with copper or SUS304, and the outer wall of carbon steel is painted with acrylic polyurethane hammer paint for corrosion prevention
The U-shaped tube adopts red copper heat exchange tube or large wave node heat exchange tube
5
Safety technical requirements: ● install a safety valve on the top of the heat exchanger, and the working pressure of the safety valve shall be consistent with the selection & ldquo; Table 1 & rdquo; To & ldquo; Table 4 & rdquo; & ldquo; in; Design pressure & rdquo; The value is the same (the safety valve shall be stated when ordering), and the installation and use of the safety valve shall comply with the provisions of the supervision regulation on safety technology of fixed pressure vessels issued by the State Administration of quality and technical supervision
● when conditions permit, an expansion pipe leading upward to the atmosphere shall be set at the top of the heat exchanger; If expansion pipe cannot be set, expansion water tank or pressure expansion tank can be set to connect with heat exchanger
● the heat exchanger shall be inspected regularly during use, and the appearance inspection shall be conducted at least once a year
Conduct internal and external inspection at least once every three years; Comprehensive inspection shall be conducted at least once every six years
The contents and requirements of inspection and inspection can be carried out with reference to the supervision regulation on safety technology of fixed pressure vessels
6
During the use of the heat exchanger, the scale of the U-shaped pipe should be cleaned regularly according to the quality and use of the heated water
When the hardness of the heated water is high, appropriate softening measures should be taken

operating instructions 1
First fill the heat exchanger and the whole hot water pipe network with cold water; 2
Turn on the hot water circulating pump of the pipe network, and open the valves on the inlet and outlet pipes of the heat medium at the same time
The temperature automatic control valve will be put into operation to evenly heat the cold water in the heat exchanger and the pipe network to the set temperature, and the system will also be put into normal operation
(Note: before opening the temperature control valve, ensure that the impurities in the heat medium pipeline have been removed)
