Heat supplying system with air source and heat pump unit matched

Abstract

The invention relates to the technical field of heat supplying through air sources and discloses a heat supplying system with an air source and a heat pump unit matched. The heat supplying system comprises an air source unit, a first connecting pipe is fixedly mounted on the right side of the air source unit, and an air source intermediate pump is fixedly mounted on the right side of the first connecting pipe. According to the heat supplying system with the air source and the heat pump unit matched, the whole heat supplying system is divided into two modes, when it is detected that the temperature of the outer side is excessively low through a temperature sensor, an electric signal is converted into a digital signal to be transmitted to a main controller through a second wire, and at the moment, the main controller controls the air source unit to start to work for heat exchanging with the atmosphere; and heat is transmitted to the air source intermediate pump through the first connecting pipe, at the moment, the heat is provided for a heat pump unit through the air source intermediate pump, then the heat is transmitted to a tail end circulating water pump through a third connectingpipe after the temperature is increased by the heat pump unit, through the tail end circulating water pump, an output pipe is utilized to deliver the heat to the home of each user for heat supplying,and the purpose of high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of air source heating, in particular to a heating system in which an air source is matched with a heat pump unit. Background technique [0002] Air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It is a form of heat pump. The use of high-level heat energy, so as to achieve the purpose of saving part of the high-level energy, the use of conventional air source heat pumps is generally used, there is a certain requirement for the minimum outdoor temperature in winter, it is suitable as a supplement for central heating, and it is responsible for the heating of single buildings or small areas. , can also be used for household heating. [0003] According to Chinese patent CN 104676937 B, a low-temperature air-source-ground-source dual-source heat pump unit and its control method include a low-pressure compressor, ...
