Problems solved by technology

However, due to the relatively high initial investment of this type of system, the application system in rural areas is usually relatively small and scattered, and the technical level of understanding and maintenance of solar energy utilization systems in rural areas is very limited, which makes the management and maintenance after operation difficult. At the same time, due to the low utilization rate of most public buildings in rural areas, the use time and number of people often change greatly, which may easily cause an imbalance between the supply and demand of the solar energy utilization system and reduce the utilization rate of solar energy

Embodiment 1

[0032] The combined system of solar air conditioning and solar centralized hot water in Embodiment 1 is a one-to-one combined system of a solar air conditioning unit and a solar centralized hot water unit. Such as figure 1 As shown, the combined system includes a solar air conditioning unit 1 and a solar concentrated water heating unit 2, the solar air conditioning unit 1 and the solar concentrated water heating unit 2 are connected through a heat exchange unit, in this embodiment, a plate heat exchange unit is selected 3 as a heat exchange unit.

[0033] In Embodiment 1, the solar air-conditioning unit 1 includes a first solar heat collection unit, a first hot water storage tank 13, a cooling unit, a buffer water tank 14 and a fan coil unit 15, and the first solar heat collection unit passes through the first circulation pipeline 61 is connected with the first hot water storage tank 13, the first heat storage coil 16 is installed in the first hot water storage tank 13, the c...

Embodiment 2

[0038] The difference between the combined system of solar air conditioner and concentrated solar hot water in embodiment 2 and embodiment 1 is that the combined system of embodiment 2 is a one-to-two combined system of solar air conditioning units and solar concentrated hot water units. Such as figure 2 As shown, the combined system includes a solar air-conditioning unit 1 and two solar centralized water heating units 2 , and the solar air conditioning unit 1 and the two solar concentrated water heating units 2 are respectively connected via a plate heat exchanger 3 .

[0039] When the hot water of the solar air-conditioning system is insufficient and the hot water of the solar centralized hot water system is surplus (generally in summer), the circulation pumps P6 and P7 are started to supplement the heat from the centralized hot water system to the solar air-conditioning system through the heat exchange unit; When the hot water of the solar centralized hot water system is i...

Abstract

The combined system of solar air conditioner and solar centralized hot water disclosed by the present invention includes several solar air conditioners and several solar concentrated hot water units, and the system can realize one-to-one and one-to-many , many-to-one, many-to-many combination, when applied, several solar air conditioning units and several solar centralized hot water units can be distributed in different villages, these solar air conditioning units and solar concentrated hot water units constitute a solar energy comprehensive Using the system, the solar air-conditioning units and solar centralized hot water units in the same village or several nearby villages can be managed in a centralized manner, and energy allocation can be carried out between each solar air-conditioning unit and solar centralized hot water unit, so that the supply and demand tend to be in balance , to maximize the use of solar energy resources. This will greatly promote the large-scale application of solar energy in rural areas and provide strong technical support for the construction of a new socialist countryside.

Description

technical field [0001] The invention relates to the technical field of solar air conditioners and solar concentrated hot water, in particular to a combined system of solar air conditioners and solar concentrated hot water and an energy allocation method thereof. Background technique [0002] At present, the application forms of solar energy in rural buildings are mainly concentrated in passive solar houses and single-family solar water heaters, which are the primary applications of solar energy. The utilization rate of solar energy is not high, and they are easily affected by the instability of solar energy resources. And some economically developed rural areas, such as the Yangtze River Delta, have gradually adopted solar air-conditioning systems or solar centralized hot water systems in public buildings and residential buildings, increasing the efficiency of solar energy use. However, due to the relatively high initial investment of this type of system, the application sys...
