Problems solved by technology

[0014] However, when the factory undergoes energy-saving transformation, the proportion of high-grade industrial waste heat decreases, and the proportion of low-grade waste heat / waste heat (temperature 20-60°C) increases. If the existing mobile heating mode is adopted, the heat extraction cost will increase and the extraction speed will decrease. Therefore, This model is difficult to match with a large number of low-grade industrial waste heat resources;
[0015] 2. Poor continuity: the conveying capacity is too small, and the turnover rate is generally taken as the unit of day;
[0016] 3. High initial investment: The total heat storage capacity of energy storage products needs to be equipped according to the daily load standard of end users, and it is impossible to replace the existing central heating system on a large scale;
[0017] 4. Low transportation efficiency: when using the heat source to user point-to-point service mode, the distribution of users is relatively scattered, some are located in remote places, and the overall transportation efficiency and reliability are affected

Embodiment 1

[0060] The heat exchange subsystem 6a of the cold / heat source system 1 and the heat exchange subsystem 6b of the heat exchange station 2 have similar structures.

[0061] The main body of the heat exchange subsystem 6 is a buffer pool 9, which is connected with the heat transfer medium circulation pipe 7 and partially overlaps, and both the buffer pool 9 and the heat transfer medium circulation pipe 7 contain the heat transfer medium 8;

[0062] The buffer pool 9 is divided into two parts: a heat exchange area 9a and a buffer zone 9b. The area where the buffer pool 9 overlaps with the heat transfer medium circulation pipe 7 is the heat exchange zone 9a, and the other areas of the buffer pool 9 are the buffer zone 9b; in the buffer pool 9 It includes one or more heat exchange rotors 10, the heat exchange rotor 10 is equipped with a phase change capsule 5 inside, and the heat exchange rotor 10 can move or rotate in the buffer pool 9 to change its position; part of the heat exchange ro...

Embodiment 2

[0083] In the case of industrial waste heat utilization, because there are many links in industrial production, the temperature and grade of waste heat generated in each link are also different, so phase change capsules with different phase change temperatures can be used to absorb different grades of heat energy. It can not only reduce the thermal energy grade loss in each absorption process, but also realize cascade utilization in the heat exchange station.

[0084] The specific plan is:

[0085] In the cold / heat source system 1, the cold / heat source is divided into multiple independent cold / heat sources of different grades according to the output temperature, and a plurality of independent cold / heat source systems are formed, and the energy grades of each cold / heat source are respectively adopted. Matched phase change capsules 5 with different phase change temperatures are used as intermediate media;

[0086] In the rapid transit system 4, the rapid transit vehicles 4b carry phas...

The heating ventilation air conditioning system comprises a cold / heat source system (1), a heat exchange station (2) and a terminal cold / heat supply network (3). The heating ventilation air conditioning system is characterized in that a fast transmission system (4) is connected with the cold / heat source system (1) and the heat exchange station (2), a phase change capsule (5) is used as an intermediate medium for fast transmission of energy, and a pipeline transmission and distribution system can be replaced.

Description

Technical field [0001] The invention relates to a phase change capsule as an intermediate medium, using a rapid transportation system to connect a cold / heat source system and a heat exchange station to realize the rapid transportation and distribution of cold / heat of HVAC, replacing pipeline transmission and distribution systems, and lifting system transmission. The ability to match and expand the scope of application of the system. It belongs to the technical field of HVAC system design and control. Background technique [0002] Regional HVAC systems usually use pipes to transport cold / heat from cold / heat sources to heat exchange stations, terminal cooling / heating networks and terminal systems, and usually use water as the heat transfer medium. Therefore, in order to improve the efficiency of the transmission and distribution system, it is necessary to increase the temperature difference between the supply and return water as much as possible, which also limits the scope of app...
