Heat supply pipe network heat pump adjusting system

Abstract

The invention relates to a heat supply pipe network heat pump adjusting system. The heat supply pipe network heat pump adjusting system comprises a boiler, and is characterized in that the boiler is connected with a primary pipe network through a pipeline, the primary pipe network exchange heat with multiple secondary pipe networks through a first heat exchanger, each secondary pipe network exchange heat with multiple third pipe networks through a second heat exchanger, the first heat exchanger compensates the temperature difference through a first temperature adjusting device, the second heat exchangers compensate the temperature difference through a second temperature adjusting device, and the first temperature adjusting device and the second temperature adjusting devices are connected with a center control computer. The heat supply pipe network heat pump adjusting system has the advantages that the control modes are diverse, control is accurate, energy is saved, the effect is obvious, the boiler provides 80% of heat, the left 20% of heat is compensated through heat pumps, and heat loss in the transportation process is reduced.

Description

technical field [0001] The invention relates to the field of urban heating pipe networks, in particular to a heat pump regulating system for the heating pipe network. Background technique [0002] With the continuous development of urban scale, the area of ​​urban central heating is increasing. Residents in large cities in Northeast China, North China, and Northwest China will basically implement centralized heating for heating except for the use of renewable energy when conditions permit. Small and medium-sized cities will develop back-pressure thermoelectricity or centralized heating transformation according to local conditions, and increase the proportion of combined heat and power in centralized heating. The automatic monitoring of the heating network is an inevitable trend in the development of the heating industry, and the correct prediction of the temperature is the key to realize the automatic control. At present, the heating system adopts climate compensation techn...
