Multi-temperature-sensor module, heat storage type hot water supply system and heat energy supply method of heat storage type hot water supply system

Abstract

The invention discloses a multi-temperature-sensor module, a heat storage type hot water supply system and a heat energy supply method of the heat storage type hot water supply system. The multi-temperature-sensor module comprises a protection cover and a temperature sensor installing support fixedly arranged in the protection cover. A plurality of temperature sensors are included and are arrangedin parallel at intervals in the length direction of the protection cover. The system adopts the multi-temperature-sensor module and comprises a water tank inner container, a heat source correlated tothe water tank inner container so as to heat water in the water tank inner container, the multi-temperature-sensor module used for collecting the temperature information of a plurality of zones in the water tank inner container, a flow and temperature sensor used for detecting the cold water flow and temperature, an environment temperature sensor used for detecting the outer environment temperature, and a controller connected with the heat source, the multi-temperature-sensor module, the flow and temperature sensor and the environment temperature sensor.

Description

technical field [0001] The invention relates to a multi-temperature sensor module, a heat storage type hot water supply system and a heat energy supply method thereof, and belongs to the field of heat storage type hot water systems. Background technique [0002] The current design method of hot water system can no longer meet the increasing needs of users for comfort, intelligence, energy conservation and environmental protection. And optimize the design from the whole system, which provides the possibility to improve the control of the hot water system, improve the user experience and increase energy efficiency. [0003] The hot water supply system can basically be divided into instant heating type and heat storage type. The so-called instant heating type means that all hot water is provided by the heating equipment from cold water, including preheating type, which can be preheated by solar energy or other heat sources. The instant heating system heats quickly, the system ...

AI Technical Summary

Problems solved by technology

The instant heating system heats quickly, the system is relatively simple, the required space is small, and the one-time investment is small, but it has the following defects: the efficiency is relatively poor in a short period of time; Or even the whole community is difficult to use due to the difficulty of transformation or high cost; the application of products with preheating has fluctuations in the application, which is not good for the equipment; low, and the opposite in summer; so convenience, comfort is not good

Water tank liner The outer wall layout of the water tank liner requires the water tank liner to be an all-metal water tank liner. This scheme is difficult to be refined due to the asymmetric thermal flow field, local thermal resistance, and uneven heat dissipation; the water tank liner is perforated. There are no special requirements for the material of the water tank liner, but there are still problems of insufficient refinement in addition to the large heat loss and the risk of leakage

[0007] Patent CN201010259177 mentions the hot water balance method to calculate thermal energy storage, but in the method, the temperature sensor is not representative of the plane where it is located, and it is only applicable to the situation where the internal hot water temperature is higher than the target water temperature. Such as small, horizontal, electric water heaters
