Air source heat pump energy-saving sunlight room and control method thereof

Abstract

The invention discloses an air source heat pump energy-saving sunlight room and a control method thereof. The air source heat pump energy-saving sunlight room comprises a sunlight room body, the sunlight room body comprises a roof glass wall, the roof glass wall is arranged in a gradient mode, and a heat collection and insulation layer is arranged below the roof glass wall and arranged along the gradient of a roof; and an air source heat pump is arranged in the sunlight room body, an air outlet of the air source heat pump is right opposite to the heat collection and insulation layer, the air source heat pump is provided with a preheating device, shutters are arranged on the two sides of the sunlight room body, and a temperature controller is arranged in the sunlight room body. According tothe air source heat pump energy-saving sunlight room, solar energy is converted into heat and stored in a phase change heat storage material, the stored heat is fully utilized by controlling the heatdissipation strength of the heat collection and insulation layer and the opening degree of the shutters, and the utilization rate of the solar energy is increased; and meanwhile, the working environment temperature of the air source heat pump is always in a proper range, and the problems that the air source heat pump is low in energy efficiency and difficult to start when the air environment temperature is too low are solved.

Description

technical field [0001] The invention relates to a sun room and a control method, in particular to an air source heat pump energy-saving sun room and a control method thereof. Background technique [0002] The sun room is also called the glass room. The sun room adopts a non-traditional building constructed of glass and metal frames to achieve the purpose of enjoying the sun and getting close to nature. The sun room is a building highly praised by those who pursue nature and fashion at home and abroad. The sun room has the advantages of transparent appearance and good light transmission effect, and is favored by more and more consumers. [0003] The traditional sun room is only a kind of building, and there are few further improvements to the energy saving and environmental protection of the sun room. Therefore, the sun room does not have the function of solar energy utilization, nor does it have the function of automatic temperature adjustment; in order to increase the use...

AI Technical Summary

Problems solved by technology

However, as the temperature drops in winter in the north, when the temperature is low (-10°C), it is difficult for the air source heat pump to achieve the effect expected in the design, the COP value is low, and the energy efficiency is low; and when the temperature is very low (-20°C ), the unit can’t even be started. At this time, it can only be started by preheating the host by means of heating (such as an electric kettle), which greatly increases energy consumption
