Abstract
The utility model belongs to energy saving control equipment and particularly relates to a thermal power station secondary side energy saving control system of an air conditioning unit. An output of a secondary side circulating pump of a heat exchanger is connected to users in parallel connection, a thermal power sensor is mounted at a user end, and an output of the thermal power sensor is connected to a frequency conversion control cabinet. The system is capable of timely and accurately controlling and adjusting running parameters of a building air conditioning system, achieving furthermost energy conservation effect under the condition of meeting indoor temperatures of 18+-2 DEG C in winter and 26+-2 DEG C in summer of each user in a thermal supply network, having energy conservation up to 60%, realizing concentration of acquisition and management of running data of a heat supply system by establishing reasonable frequency conversion control running scheme of an air conditioner fan and the circulating pump, realizing unattended air conditioning unit, and saving a large amount of labor material.
Description
Technical field
The utility model belongs to energy-saving control apparatus, particularly a kind of air-conditioning unit thermal substation secondary side energy-saving control system.
Background technology
According to relevant departments climatic data statistical analysis is in recent years learnt, because global climate " warms ", climate change is bigger, this has been caused the great attention of each big city heating refrigeration trade management department, renewal of the equipment and management in more should strengthening producing for northern city heat supply enterprise are to reduce unnecessary energy waste.
We know that the spring and autumn in every year exists the seasonal temperature difference, existence in winter in summer difference warm in nature in the daytime changes.Blower fan in the air-conditioning system, the long-term constant speed running of water pump will cause a large amount of energy wastes and equipment loss.If do not take conservation measures, energy waste and equipment loss just will continue to enlarge.
Pass through to adopt air-conditioning integrated monitoring dispatching patcher for the building air-conditioner system, can control and regulate the operational factor of building air-conditioner system in time, exactly, in satisfying heat supply network under the prerequisite in indoor temperature winter/summer 18 ± 2/26 ℃ ± 2 of each user, reach energy-saving effect to greatest extent, so not only improve the supply capacity of air-conditioning system, and reduce the discharging of pollutant.According to this toward the experience of project, adopt the operating mode balance of microcomputer integrated monitoring dispatching patcher by realizing that air-conditioning is once netted each air-conditioning unit, make air-conditioning system by season variations in temperature, daytime temperature change the energy-saving and frequency-variable operation, thereby can obtain 15% expansion energy supply power, can eliminate most of family uneven in temperature; By realizing that the temperature Compensation Regulation can save energy more than 13%; By formulating the VFC operating scheme of rational air-conditioning draught fan, circulating pump, can economize on electricity reaches 60%; By realizing the concentrated collection and the management of heating system service data, can realize the unmanned of air-conditioning unit, save the great amount of manpower resource.
The utility model content
The purpose of this utility model is at the blower fan in the existing air-conditioning system, water pump can not exist the seasonal temperature difference with spring and autumn, exist winter in summer difference warm in nature in the daytime to change and change, long-term constant speed running, the deficiency of a large amount of energy wastes and equipment loss will be caused, a kind of air-conditioning unit thermal substation secondary side energy-saving control system is provided, it is characterized in that, a hot water side of the heat exchanger of described air-conditioning unit thermal substation secondary side energy-saving control system connects the hot water control valve, secondary side upper end at heat exchanger connects circulating pump, the output of circulating pump connects user load in parallel, at the user load end heating power sensor is installed, the output of heating power sensor is connected to the VFC cabinet.
Described VFC cabinet connects the control end of hot water control valve, circulating pump respectively, and the output of heating power sensor is connected to the control interface of VFC cabinet.
The by-pass valve control of contacting separately in the pipeline of described each user load.
The beneficial effects of the utility model are that air-conditioning system is adopted air-conditioning integrated monitoring dispatching patcher, can control and regulate the operational factor of building air-conditioner system in time, exactly and heating power sensor and polyphone are installed at the user load end, the output of heating power sensor is connected to the VFC cabinet, the by-pass valve control of contacting separately in the pipeline of each user load, from main control, satisfy the prerequisite standard in the indoor temperature winter/summer 18 ± 2/26 ℃ ± 2 of each user in the heat supply network, economize on electricity reaches 60%; By realizing the centralized management of heating system service data, can realize the unmanned of air-conditioning unit, save the great amount of manpower resource.
Description of drawings
Fig. 1 is a thermal substation secondary side Energy Saving Control schematic diagram.
The specific embodiment
The utility model provides a kind of air-conditioning unit thermal substation secondary side energy-saving control system, thermal substation secondary side Energy Saving Control schematic diagram as shown in Figure 1.Among the figure, a hot water side at the heat exchanger 4 of system connects hot water control valve 1, secondary side upper end at heat exchanger 4 connects circulating pump 3, the output of circulating pump 3 connects user load 6 in parallel, the by-pass valve control 5 of contacting separately in the pipeline of each user load, the user is temperature in main control room.At the user load end heating power sensor 7 is installed, the output of heating power sensor 7 is connected to VFC cabinet 2.VFC cabinet 2 connects the control end of hot water control valve 1, circulating pump 3 respectively.Indoor temperature data by the collection user load 6 of heating power sensor 7, be delivered to the control interface of VFC cabinet 2, the temperature range that VFC cabinet 2 is predetermined according to Various Seasonal, control hot water control valve 1 the flow and the rotating speed of circulating pump 3 respectively, with the standard-required in indoor temperature winter/summer 18 ± 2/26 ℃ ± 2 of satisfying each user in the heat supply network, overcome the defective that blower fan, the long-term constant speed running of water pump cause a large amount of energy wastes and equipment loss.The frequency-variable controller of VFC cabinet is chosen the series of products into ACS510.
