Embodiment 1

[0032] Such as figure 1 As shown, when the air conditioner is in heating mode and solar auxiliary heating is turned on, the four-way valve 9 is in the second position (even if the air conditioner is in the heating position), the first control valve 6 is in the open state, and the second control valve 7 is in the Open state and the third control valve 8 is in the closed state, the main electronic expansion valve 10 and the auxiliary electronic expansion valve 11 are both open, at this time, according to figure 1 As shown by the arrow, the solar heating device and the air-cooled heat exchange device are connected in parallel and used as an evaporator for heating at the same time, which increases the evaporation pressure of the air conditioning system and improves the heating effect of the air conditioner under low temperature conditions.

Embodiment 2

[0034] Such as figure 2 As shown, when the air conditioner is in heating mode and the solar auxiliary heating is turned off (for example, when there is no sunlight to provide a heat source on a rainy day or a snowy day), the four-way valve 9 is in the second position (even if the air conditioner is in the heating position), The first control valve 6 is in the open state, the second control valve 7 is in the closed state, and the third control valve 8 is in the closed state. The main electronic expansion valve 10 is opened and the auxiliary electronic expansion valve 11 is closed. figure 2 As shown by the arrow, the air-cooled heat exchange device alone serves as an evaporator for heating.

Embodiment 3

[0036] Such as image 3 As shown, when the air conditioner is in the cooling mode, the four-way valve 9 is in the first position (even if the air conditioner is in the cooling position), the first control valve 6 is in the open state, the second control valve 7 is in the closed state, and the third control valve 8 is in the closed state, the main electronic expansion valve 10 is opened and the auxiliary electronic expansion valve 11 is closed. image 3 As shown by the arrow, the air-cooled heat exchange device alone serves as a condenser for cooling.

Abstract

The invention belongs to the technical field of air conditioners, and provides an air conditioning system and an air conditioner. The air conditioning system and the air conditioner are used for solving the problem that the heating effect of an existing air conditioner cannot be improved suitably. The air conditioning system comprises an indoor unit, an outdoor unit and a compressor. A loop-lockedcirculation main path is formed by the indoor unit, the outdoor unit and the compressor. The air conditioning system further comprises a solar heating device connected with the outdoor unit in parallel. The solar heating device can assist the outdoor unit with heating when the air conditioner carries out heating, and has the function of being used instead of the outdoor unit when the air conditioner defrosts. Because the solar heating device can assist the outdoor unit with heating when the air conditioner carries out heating, and in other words, the solar heating device can carry out heatingcompensation on the outdoor unit when the air conditioner carries out heating, it is guaranteed that the outdoor unit carries out continuous heating when the air conditioner defrosts, it is avoided that indoor unit heating is interrupted because the outdoor unit of the air conditioner defrosts, more energy of the air conditioner is saved, and the user experience is improved.

Description

Technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner system and an air conditioner. Background technique [0002] Air conditioners are equipment that can cool / heat indoors. With the continuous development of economy, air conditioners have become a common life product for the general public. Especially in large commercial and residential offices, multi-unit air conditioners have become standard. In winter, air conditioners generally suffer from poor heating effects. Especially in northern areas, the heating effect of air conditioners cannot meet the heating needs of users. Even when the temperature is lower, the air conditioning system may be faulty. The air conditioner is not working properly. At the same time, during the heating operation of the air conditioner in winter, the outdoor unit also needs to continuously perform defrosting operations, which causes the air conditioner to be unable to cont...
