Detailed Description
The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings for the purpose of facilitating understanding and understanding of the technical solutions of the present invention.
The technical scheme of the invention aims to improve the situation that the energy consumption of the traditional hot water heating system is high, and the traditional heating control mode is subjected to referential analysis, so that the hot water heating system in the building and the climate compensation method thereof are obtained innovatively, and the energy-saving operation of the system is realized. According to the technical principle, the innovative scheme can automatically control the water supply temperature according to the change of the outdoor temperature and the requirements of different time set by a user on the indoor temperature and a set curve, so that the automatic climate compensation of the outdoor temperature on the water supply temperature of a heat supply system is realized, and the energy waste caused by overhigh/low room temperature is avoided. By using the variable flow control system in the air conditioning water system for reference in a hot water heating system, the objective problem of excessive energy consumption can be well solved.
As shown in the schematic diagram of fig. 1, firstly, from the summary of hardware related to the hot water pipeline in the hot water heating system to the main hot water pipeline, an electric control valve 3 and an immersion temperature sensor 4 are provided, the building is provided with an outdoor climate temperature sensor 2, a climate compensator 1 is newly added to the hot water heating system, and the signals collected by the immersion temperature sensor 4 and the outdoor climate temperature sensor 2 are both connected to the climate compensator 1 for detecting the heating water temperature and the outdoor real-time temperature, respectively, the electric control valve 3 is driven to be connected to the climate compensator 1 for adjusting the hot water supply amount, the heating unit 5 is connected with the climate compensator 1 through bidirectional signals, and the user is synchronized to preset the indoor temperature requirement and adjust the water temperature at the supply point. Moreover, the climate compensator is a microprocessor with computing capability and has control output of PID regulation system.
The function realization principle of the hot water heating system is as follows: when outdoor changes, the corresponding temperature sensor feeds back signals to the climate compensator, and in the heating time interval, the water supply temperature also changes correspondingly in order to meet the relative stability of the indoor temperature. Namely, the set value (ideal value) of the heating water temperature is automatically corrected, the set value is compared with the actual water supply temperature, and the PID adjustment is carried out on the electric valve by taking the comparison difference as the reference. For example: when the outdoor temperature is reduced, the heating water temperature is properly increased in order to maintain the original indoor temperature, and at the moment, the climate compensator automatically increases the hot water supply amount supplied to the heating unit so as to properly increase the heating water temperature; when the outdoor temperature rises, the heating water temperature is properly reduced to avoid the indoor overheating phenomenon, and at the moment, the system automatically reduces the hot water supply amount to the heating unit to reduce the output load of the heating unit.
Typically, the immersion temperature sensor requires only one hot water line located near the supply point for low-volume applications. However, in order to control the supply amount of heating hot water for high distribution and perfect distribution, the number of the outdoor climate temperature sensors is more than two, and the outdoor climate temperature sensors are distributed on the outer side of the building near the set points corresponding to more than two indoor temperature demands. The immersion temperature sensors can be configured in a plurality of ways and distributed in a hot water pipeline close to a supply point and a return point, and all the immersion temperature sensors at two positions are connected to the input end of the climate compensator. And external signals such as return water temperature and the like are introduced as feedback values to correct a heating water temperature curve in real time during multipoint outdoor temperature monitoring, so that the aim of energy-saving operation is fulfilled.
Furthermore, the practical applicability of the climate compensation method is understood from the specific operation process of the hot water heating system, and the basic preparation work on hardware is firstly completed: an electric regulating valve and an immersion temperature sensor are arranged on the basis of the positioning of a hot water pipeline for indoor heating, an outdoor climate temperature sensor is arranged on the basis of the outer wall of a building, a climate compensator is additionally arranged in a hot water heating system, and the climate compensator, each temperature sensor, the electric regulating valve and a heating unit are connected into a whole; the specific setting, operation and operation steps are developed as follows.
S1, presetting indoor temperature requirements by a user, starting a heating unit to heat by using a hot water pipeline, and transmitting acquired data into the climate compensator in real time by the immersion temperature sensor. The preset indoor temperature requirements are different from person to person, the temperature resistance and comfortable temperature ranges of different persons at the same outdoor temperature in the same season are different, and the outdoor temperature at different time intervals or in sudden climate conditions in each day is lack of accurate predictability. Therefore, users can set their comfortable temperature requirements at different periods according to their preferences, and the settings can be transmitted to the heating unit through a wall panel or a remote controller, and also can be transmitted to the climate compensator through synchronous interaction.
S2, recording the outside air temperature of the corresponding position and orientation of the building in real time by an outdoor climate temperature sensor, and immediately transmitting the acquired data into a climate compensator; the different orientations of the building at the same time may have differences of sunny and backsun, and the high and low floors may have slight differences. Therefore, the temperature sensor is suitable for being arranged in a multi-way mode around all sides and all height positions of a building, and therefore hot water heating can be accurately carried out on indoor rooms for purpose. For example, for a room with a high heating temperature demand, the electric regulating valve is independently controlled in a branch way, the hot water supply is increased, and the hot water supply is correspondingly reduced.
And S3, correcting the heating water temperature through calculation based on the data transmitted by each temperature sensor by the climate compensator, comparing the corrected heating water temperature with the actual water temperature at the supply point, and performing lifting regulation and control on the water temperature at the supply point of the heating unit and hot water supply regulation and control on the electric regulating valve by taking the temperature difference as a reference. So as to reduce the output load of the heating unit.
In summary, with reference to the detailed description and the functional implementation of the illustrated embodiments, the technical solution of the present invention has the following significant effects: (1) the system responds timely. The climate compensator can automatically correct the set value of the heating water temperature by collecting the outdoor temperature, then compares the set value with the actual water supply temperature, and carries out PID adjustment on the electric valve by taking the comparison difference as a reference.
(2) The system safety is high. The set point water supply temperature and the valve opening degree of the system are controlled according to the end requirement, the operation amount of the whole control system is effectively simplified, the system stability is good, and the improvement of the safety of a laboratory is facilitated.

The climate compensator realizes the automatic climate compensation function of the change of the heating water temperature and the outdoor temperature in the heating system by controlling the opening of the electric regulating valve, realizes the aim of heating according to requirements, and realizes the energy conservation while ensuring the heating quality.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by using equivalent substitutions or equivalent transformations fall within the scope of the present invention.
