Embodiment 1

[0033] Such as figure 1 Shown is a specific connection structure of an air-conditioning system with a continuous heating function during the defrosting process proposed by this embodiment. The air conditioning system includes a compressor 1 and a liquid storage tank 2, the liquid storage tank 2 is connected to the compressor 1, and necessary separation components such as a gas-liquid separator and an oil-liquid separator can be arranged between the two.

[0034] The specific connection structure of the air conditioning system in this embodiment is that after the outlet end of the compressor 1 is connected to the indoor heat exchanger 4 through the four-way reversing valve 3, the first throttling device, the outdoor heat exchanger 6, and the second throttle device are connected in series in sequence. Throttle device, auxiliary heat exchanger 8, and then connected to the suction end of compressor 1 through four-way reversing valve 3. Wherein, the first throttling device in this...

Embodiment 2

[0041] This embodiment is roughly the same as the connection structure of the air-conditioning system in Embodiment 1, the difference is that no check valve is set in the connection structure of the air-conditioning system in this embodiment, so that the auxiliary heat exchanger can The auxiliary outdoor heat exchanger realizes the effect of evaporation or condensation.

Abstract

The invention discloses an air conditioning system with the continuous heat supply function in the defrosting process. The air conditioning system comprises an outdoor heat exchanger. The rear end of the outdoor heat exchanger is sequentially connected with a second throttling device and an auxiliary heat exchanger in series. The second throttling device and the auxiliary heat exchanger are connected in series and then connected with second two-way valves in parallel. The second two-way valves form a second bypass branch. A first throttling valve and the outdoor heat exchanger are connected in series. The two ends of the first throttling device are connected with first two-way valves in parallel, and the first two-way valves form a first bypass branch. The air conditioning system is provided with an auxiliary heat exchanger and an auxiliary draught fan. When a defrosting program operates, the outdoor heat exchanger conducts defrosting operation, the auxiliary heat exchanger serves as an evaporator, the heating function of an air conditioner is achieved, and therefore it is guaranteed that the air conditioner can continuously supply heat in the defrosting process, the experience of a user is better when the user uses the air conditioner in winter, and the market competitiveness of products is enhanced.

Description

technical field [0001] The invention relates to the field of air conditioning systems, and more specifically discloses an air conditioning system capable of continuously supplying heat during the defrosting process of the air conditioner. Background technique [0002] The existing heating defrosting technology absorbs the indoor temperature during the defrosting process, forming a reverse cycle (that is, the indoor becomes a cooling environment), resulting in fluctuations in the indoor environment and poor user experience. [0003] Even if a relatively new defrosting control system is adopted, it can only ensure that the air conditioner does not absorb heat from the indoor environment during the heating process, but it cannot achieve continuous heating and cannot meet the user's requirements for air conditioner cooling in winter. [0004] Therefore, the market urgently needs an air-conditioning system capable of continuously supplying heat during the defrosting process of th...
