Family splitting control device for central heating of building units and heating system

Abstract

The invention discloses a family splitting control device for central heating of building units and a heating system. By adopting the family splitting control device for central heating of the building units and the heating system, water flow can be adjusted, the heating temperature can be controlled, and the utilization rate of heat energy can be greatly increased. The heating system comprises a heat source water supply system, a plurality of family splitting control devices and an indoor temperature controller, wherein the family splitting control devices are communicated with the heat source water supply system, and the indoor temperature controller is in communication connection with the family splitting control devices. Each family splitting control device comprises a box, a plate heat exchanger, a control device, a heat source water circulation loop, a heat supply water circulation loop, a proportion regulating valve, a temperature sensor and a water pump, wherein the plate heat exchanger and the control device are arranged in the box; the heat source water circulation loop and the heat supply water circulation loop are communicated with the plate heat exchanger; the proportion regulating valve is arranged on the heat source water circulation loop; the temperature sensor and the water pump are arranged on the heat supply water circulation loop; the control device is electrically connected with the proportion regulating valve, the temperature sensor and the water pump.

Description

technical field [0001] The invention relates to heating equipment, in particular to a household control device and a heating system for centralized heating of building units. Background technique [0002] The heating method in northern my country is mainly based on centralized heating. The heat source is cogeneration waste heat or large coal-fired and gas-fired boilers. The unit is a few square kilometers, and the unit is a residential area. An independent boiler room is set up. One for one use and one for standby, the thermal drive adopts a large-lift, large-flow circulating pump, and the main heating pipe must be arranged, and high-temperature water circulation is adopted, and a secondary heat exchange large plate is installed in the community or in the building, and then a medium-sized one is used. Circulating pumps are transported to each apartment unit, which causes serious heat loss and waste of energy. The laying and maintenance costs of the heat pipe network are high, ...

Problems solved by technology

[0002] The heating method in northern my country is mainly based on centralized heating. The heat source is cogeneration waste heat or large-scale coal-fired or gas-fired boilers. The largest unit is a few square kilometers, and the smallest unit is a residential area. Set up an independent boiler room. One for one use and one for standby, the thermal drive adopts a large-lift, large-flow circulating pump, and the main heating pipe must be arranged, and high-temperature water circulation is adopted, and a secondary heat exchange large plate is installed in the community or in the building, and then a medium-sized one is used. Circulating pumps are transported to each apartment unit, which causes serious heat loss and waste of energy. The laying and maintenance of the heat pipe network are costly and expensive. Large boilers are used, which must be reported for inspection and inspection every year, and special personnel are required to manage them. The needs of modern real estate project development and other issues

Although some residential quarters adopt household metering, due to the different north-south orientations of the buildings themselves, the heating load of each household is quite different, resulting in an unbalanced heating power. Some households are particularly hot in winter and have to open windows. Energy: some households do not have enough heat in their homes, there are many complaints, and it is difficult for the heating company to charge fees. Every winter heating season, various northern cities often report that the heating effect is not good, and the residents have great opinions, which has caused many social conflicts
