Abstract

The invention is a kind of system integrated by three casing pipe solar energy with energy storage and air-source heat pump, it relates to a kind of integrated system of heat pump. The aim of the invention is to settle the problem of application of air-source heat pump which makes network load rise gradually, ability of supplying heating of heat pump in winter and demanding of load of buildings not in-phase and makes efficiency of solar heat pump's collection low in the central air-conditioning system, at the same time, the cost is higher and it is often influenced by the weather. Intake of the first energy storage heat exchanger, Intake of the second energy storage heat exchanger and intake of the third energy storage heat exchanger connect with the second pipeline separately. The invention realizes electrical load's peak shifting and valley filling , balances heat pump heat-supplying load day and night in winter, adopts the running pattern of multiple heat sources which include air source, solar power and heat storage source, makes up for existing scarcity when single heat source runs, the air-condition can work at full load as much as possible. The invention can realize 5 kinds of operation patterns in summer and 4 kinds in winter.

Description

technical field [0001] The invention relates to a heat pump integrated system, in particular to a solar energy and air source integrated heat pump system with dual functions of phase change accumulators for heat storage in winter and cold storage in summer. Background technique [0002] With the increasing application of air source heat pump units, the existing problems are gradually reflected in the process of use: (1) The use of air conditioners in summer is concentrated, resulting in concentrated power loads and exacerbating the peak-to-valley difference in urban power grids. Since air conditioners are mainly operated during the daytime in summer, the load on the power grid continues to rise, resulting in a continuous increase in the peak load of the power grid. (2) The heating capacity of the heat pump in winter is not synchronized with the load demand of the building, and there is a contradiction between supply and demand. Affected by the temperature difference between...
