Problems solved by technology

However, one of the main disadvantages of air source heat pumps is that the heating capacity and coefficient of performance of heating supply decrease with the decrease of outdoor temperature, so its use is limited by the ambient temperature, and it is generally suitable for areas with the lowest temperature above -10°C
When heating at low temperature, the temperature of the air outlet is relatively low, and people feel that the cold wind is blowing, but it will feel colder and colder, and the comfort is poor

Abstract

The invention provides a solar air conditioner and a control method thereof. The comfortableness of the air discharging temperature during the low-temperature running can be improved, and the refrigeration efficiency can be also improved. According to the technical scheme, the solar air conditioner comprises a compressor, an indoor machine heat exchanger, an outdoor machine heat exchanger, a solar module and a four-way valve, wherein the compressor is provided with an air suction opening and an air exhaust opening; and the solar module is connected between the four-way valve and the air exhaust opening of the compressor. The invention also provides the control method for the solar air conditioner. According to the solar air conditioner, a heat pump technology and a solar technology are combined, so that the low-temperature heating performance of a heat pump air conditioner is improved, the air discharging temperature during the low-temperature heating is increased, and human body feels more comfortable. By the adoption of modular design and the independent computer control, the solar module can be reasonably used in both a refrigeration mode and a heating mode; the generality of the air conditioner is improved; and the solar air conditioner is environment-friendly and economic.

Description

technical field [0001] The invention belongs to the technical field of solar air conditioners, and in particular relates to a solar air conditioner and a control method thereof. Background technique [0002] The air source heat pump is an energy-saving and environmentally friendly heating technology based on the reverse Carnot principle. Heating or hot water supply, so it has low energy consumption, high efficiency, fast speed, good safety, strong environmental protection, and continuous heating or hot water supply. However, one of the main disadvantages of air source heat pumps is that the heating capacity and coefficient of performance of heating supply decrease with the decrease of outdoor temperature, so its use is limited by the ambient temperature, and it is generally suitable for areas with the lowest temperature above -10°C. When heating at low temperature, the temperature of the air outlet is relatively low, and people feel that the cold wind blows, but it will fee...
