Example Embodiment

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0021] see in conjunction figure 1 As shown, according to the embodiment of the present invention, the heat recovery external machine system includes a compressor 1, a high-pressure air pipe 2, and a first branch 5, a second branch 6, and a third branch 7 arranged in parallel. The first branch 5 The first outdoor heat exchanger 8 is arranged on the upper side, and the second outdoor heat exchanger 9 is arranged on the second branch 6. When the air conditioning system is in the low-temperature cooling mode where the outdoor temperature is lower than the first preset In the high-temperature heating mode of the second preset temperature, one of the first branch and the second branch is connected, the other branch is disconnected, and the third branch is connected to the high-pressure gas ...

Abstract

The invention discloses a heat recovery external unit system and an air conditioner system. The heat recovery external unit system comprises a compressor (1), a high-pressure air pipe (2), a first branch (5), a second branch (6) and a third branch (7); the first branch (5), the second branch (6) and the third branch (7) are arranged in parallel; a first outdoor heat exchanger (8) is arranged on the first branch (5); a second outdoor heat exchanger (9) is arranged on the second branch (6); and when the air conditioner system is positioned in a low temperature refrigeration mode where the outdoor temperature is lower than a first preset temperature, or is positioned in a high temperature heating mode where the outdoor environment temperature is higher than a second preset temperature, one of the first branch (5) and the second branch (6) is connected and the other one is disconnected, and the third branch (7) communicates with the high-pressure air pipe (2), wherein the first preset temperature is lower than the second preset temperature. According to the heat recovery external unit system, a situation that rapid refrigeration is realized in a low temperature environment or rapid heating is realized in a high temperature environment can be ensured, and the use comfort of an air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat recovery external unit system and an air conditioning system. Background technique [0002] With the development of society and the consumption of energy, energy saving, environmental protection and sustainable development have become important issues that need to be solved urgently in today's society. In the field of air conditioning, the heat recovery multi-connected outdoor unit can cool down the room that needs to be cooled. At the same time, the evaporator of the indoor unit that needs to be heated in other rooms is transformed into a condenser, using the heat generated by the condensation of the refrigerant. The indoor temperature can be heated; a hot water generator can also be connected to the indoor side to heat domestic water to a certain extent, realizing the secondary utilization of energy, greatly reducing energy waste, and at the same time slowing do...
