Thermal station energy saving device with double adjustment functions

Abstract

The invention belongs to the energy saving field of central heating, and discloses a thermal station energy saving device with double adjustment functions. The thermal station energy saving device with the double adjustment functions is characterized by comprising a double adjustment control master machine (1), an outdoor temperature sensor (2), a heat exchanger (3), a secondary water supply temperature sensor (6), a secondary return water temperature sensor (7), a secondary bypass pipe (4), a one-way electric adjusting valve (5), a secondary mixed water temperature sensor (8), a secondary mixed water pressure sensor (10), a secondary return water pressure sensor (11) and a water pump inverter (9). According to parameters obtained through monitoring of the outdoor temperature sensor, the open degree of the electric adjusting valve on the secondary bypass pipe is adjusted, a part of return water on the secondary side is enabled to enter the heat exchanger for heat exchanging, and the other part of the return water on the secondary side passes through the bypass pipe and can reach a predicted water supply temperature after being mixed with other water. According to parameters obtained through monitoring of the secondary mixed water pressure sensor and the secondary return water pressure sensor, an instruction is sent to the water pump inverter to adjust the running frequency of a water pump, and therefore the flow rate of the secondary water supply is changed. The thermal station energy saving device with the double adjustment functions achieves climate compensation control, supplies heat according to the needs of users, and reduces the quantity of electricity consumed by the water pump in the operation process.

Description

technical field [0001] The invention belongs to the technical field of central heating and heat supply energy saving, and in particular relates to an energy saving device for a thermal station with climate compensation and frequency conversion dual adjustment functions. Background technique [0002] The heat sources of the heating system (including boilers and heat exchange stations) are designed and constructed according to the extreme cold weather parameters. Without adjustment means, when the outdoor temperature rises or the solar radiation conditions are good, the end users will overheat, resulting in Waste of heat. Climate compensation is an energy-saving device that realizes on-demand heating. It adjusts the water supply temperature according to changes in outdoor air temperature, reduces the user's heat supply, reduces terminal overheating, and achieves energy saving and consumption reduction. [0003] At present, most of the climate compensation devices used in engin...

Problems solved by technology

However, in actual engineering projects, especially large municipal heating network projects, it is impossible to realize the flow regulation and control of the primary side of the thermal station. In order to achieve the purpose of climate compensation, it is necessary to develop a climate compensation cabinet for secondary side regulation and control.
