Compartment temperature control adjusting device and control system based on water mixing principle

Abstract

The invention discloses a compartment temperature control adjusting device and control system based on a water mixing principle, and the compartment temperature control adjusting device comprises a plurality of water mixing device inlets, a blended water inlet, a plurality of water mixing device outlets, a plurality of electric water mixing adjusting valves and a water mixing pump which are communicated through pipelines. Supplied water at the inlet of the water mixing device and blended water at the blended water inlet enter the electric water mixing regulating valve and then are mixed and regulated, the mixed water flows into a cooling or heating system through the outlet of the water mixing valve and the outlet of the water mixing device in sequence, and the temperature sensors are mounted at the outlet of each water mixing valve and the outlet of the water mixing pump. The air conditioning system is small in occupied space, compact in structure and convenient to install, the water supply temperature and the water supply flow are controlled through multiple branches under the two states of heat supply in winter and refrigeration in summer of the air conditioning system, and the application range is wider; the indoor temperature can be quickly reached, and the set temperature can be stably maintained.

Description

technical field [0001] The invention relates to the technical fields of heating, ventilation, heating and refrigeration, in particular to a room-by-chamber temperature control and adjustment device based on the principle of water mixing. Background technique [0002] With the improvement of the income level of Chinese people, people's requirements for comfort are also constantly improving, and water, electricity and heating are indispensable as supporting infrastructure. However, with the arrival of the annual heating (cold) season, the problem of heating (cold) is particularly prominent. [0003] Most of the current residential buildings adopt the centralized heating (cooling) method. However, different groups of people have different temperature requirements, and the heat exchange (cold) station can only provide a temperature output for climate change, so it will The supply temperature of each building, each floor, each household, and even each room is the same, which obv...

AI Technical Summary

Problems solved by technology

However, for other forms such as radiant heating, cooling, and fan coils, it can only be adjusted by adjusting the opening of the valve.

Our experiments have proved that the control effect of this method is not good. Due to the influence of thermal inertia, the indoor temperature will not drop (or rise) immediately after the solenoid valve is closed, but has a certain hysteresis. After opening, the indoor temperature will not rise immediately, and the indoor temperature will oscillate, with a large deviation

[0005] There are room-by-room temperature control equipment and systems for radiant floor heating on the market, but there is no room-by-room temperature control device that can serve both heating and air-conditioning systems in winter and cooling and air-conditioning systems in summer
