Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heating, especially to a double-system heat exchange device. BACKGROUND

[0002] The common heating method in the central heating industry is to use water as the medium to transport the heat of the heat source to the heating device through the heat supply pipe network, which is commonly known as the hot water heating pipe network. However, the traditional hot water heating pipe network. At present, two heating devices are often heated by a set of heating system, that is, a double-system heat exchange device.

[0003] However, in the existing double-system heat exchange device, it is often divided into two categories, specifically:

[0004] The first type of existing double-system heat exchange device: refer to the attached Figure 1 , including heat exchange unit host 1, the heat exchange unit host 1 includes mutually coordinated absorber 2, evaporator 3, generator 4 and condenser 5; It also includes heat exchanger one 6 and heat exchanger two 7 connected with the heat exchange unit host 1; Heat exchanger one 6 and heat exchanger two 7 are both water-water plate heat exchangers; The generator 4 is provided with a primary network water inlet 8 for the primary network water to enter; The evaporator 3 is provided with a primary network water outlet 9; The heating device includes a first heating system and a second heating system; The first heating system includes a secondary network water inlet and a secondary network water outlet; The secondary network water in the first heating system enters from the secondary network water inlet, and is divided into two ways, one way through the absorber 2 and the condenser 5 to increase the temperature, and is delivered to the secondary network water outlet; The other way through the heat exchanger one is delivered to the secondary network water outlet. The actual load of the first heating system is the sum of the load of the heat exchanger one 6 and the load of the heat exchange unit host. The actual load of the heat exchanger one 6 accounts for about half of the total actual load. The second heating system includes: a secondary network water second inlet 12 and a secondary network water second outlet 13; The secondary network water in the second heating system enters from the secondary network water second inlet 12, and all enters the heat exchanger two 7, and then flows out to the secondary network water outlet 11. The actual load of the second heating system is the actual load of the heat exchanger two 7.

[0005] In this way, when the flow of primary network water supply increases, the flow of primary network water supply in heat exchanger one 6 and heat exchanger two 7 will also increase synchronously, which will affect the temperature of the heat source in heat exchanger one 6 and heat exchanger two 7, and greatly change the heating degree of the secondary network return water of the two heating systems. This prior art cannot effectively adjust the actual load of the first heating system and the second heating system separately.

The double-system heat exchange device further comprises an absorber partition plate 31, which is arranged in the absorber water chamber of the absorber 2. The absorber partition plate 31 can divide the absorber water chamber into a first absorber water chamber 32 and a second absorber water chamber 33, and the first absorber water chamber 32 and the second absorber water chamber 33 are independent of each other and are not connected to each other. The primary network pipeline system comprises a primary network water supply pipeline 34, which is connected in series with the generator 4 and the evaporator 3 along the water supply direction. The primary network water supply is fully extracted by the generator 4 and the evaporator 3.

The actual load of the second heating pipeline 36 is the sum of the load of the second heat exchanger 41 and the load of the second subunit.

[0042] When the actual loads of the first heating pipe 35 and the second heating pipe 36 are adjusted, the primary network water flow of the first heat exchanger 40 and the second heat exchanger 41 can be adjusted by the flow regulating valve, the temperature at the heat source of the first heat exchanger 40 and the second heat exchanger 41 is changed, the heating degree of the secondary network return water of the first heat exchanger 40 and the second heat exchanger 41 is adjusted, and the actual loads of the first heating pipe 35 and the second heating pipe 36 are adjusted. Meanwhile, when the actual load of one of the first heating pipe 35 and the second heating pipe 36 is far less than the design load (the required load), the flow of the secondary network return water into the corresponding absorption heat exchanger unit can be reduced, i.e., the flow regulating valve on the unit branch is adjusted, so that the actual load is changed; the flow of the secondary network return water into the corresponding heat exchanger of the first heating pipe 35 and the second heating pipe 36 can also be adjusted, i.e., the flow regulating valve on the heat exchanger branch is adjusted, so that the actual load of the first heating pipe 35 and the second heating pipe 36 is changed.
