Description
技术领域 technical field
本实用新型专利涉及地暖控制器生产领域，具体提供一种能够直接连入小区集中供暖系统并具有超温保护功能的地暖控制器。 The utility model patent relates to the field of floor heating controller production, and specifically provides a floor heating controller that can be directly connected to the central heating system of a residential area and has an over-temperature protection function.
背景技术 Background technique
随着社会的不断发展，科学技术的不断进步，智能化控制设备越来越普及，作为现有的取暖设备中，地暖以其优越的性能效果被不断的普及推广，而在地暖的使用过程中，控制器是一个不可或缺的重要控制部件。 With the continuous development of society and the continuous progress of science and technology, intelligent control equipment is becoming more and more popular. As the existing heating equipment, floor heating has been continuously popularized and promoted due to its superior performance and effect. In the process of using floor heating , the controller is an indispensable and important control component.
现有技术的地暖控制器一般仅适用于自身配备锅炉的独立水暖系统，没有考虑利用小区集中供热系统热水进行采暖所面临的问题。因此主要有以下两个显著的不足：一、小区集中供暖系统的热水温度通常在40～90°C范围内变化，而一般地暖盘管材料的耐温上限为60°C，超过这个上限温度会显著减少地暖盘管的使用寿命，现有的地暖控制器没有考虑到这一问题，因此不能直接使用小区集中供暖系统的热水；二、当前的地暖控制器没有考虑用户采暖用热的计量问题，无法满足当前分户计量、按量收费的要求。 The floor heating controllers in the prior art are generally only suitable for independent water heating systems equipped with boilers, and do not consider the problems faced by using hot water from the central heating system of residential quarters for heating. Therefore, there are mainly two significant deficiencies as follows: 1. The temperature of hot water in the district central heating system usually changes within the range of 40-90°C, while the upper limit of the temperature resistance of the general floor heating coil material is 60°C. It will significantly reduce the service life of floor heating coils. The existing floor heating controllers do not take this into account, so they cannot directly use the hot water from the central heating system in the community; 2. The current floor heating controllers do not consider the measurement of user heating heat The problem is that it cannot meet the current requirements of household metering and volume-based charging.
因此，提供一种可在小区集中供热系统热水温度大幅波动时，确保进入地暖盘管的热水温度在允许温度范围内，从而保证地暖盘管的安全和寿命；同时通过自动控制采暖热水的流量，维持住户房间温度稳定在用户的设定值，改善地暖系统的舒适性和经济性的新型地暖控制器，已经是一个值得研究的问题。 Therefore, to provide a method that can ensure that the temperature of hot water entering the floor heating coil is within the allowable temperature range when the hot water temperature of the district central heating system fluctuates greatly, thereby ensuring the safety and life of the floor heating coil; at the same time, by automatically controlling the heating heat The flow of water, maintaining the temperature of the resident's room at the user's set value, and a new type of floor heating controller to improve the comfort and economy of the floor heating system are already a problem worth studying.
