Embodiment 1

[0051] This embodiment provides an air-conditioning system with uninterrupted heating, figure 1 It is a structural diagram of an air conditioning system according to an embodiment of the present invention, such as figure 1 As shown, the air conditioning system includes: a compressor 11, an indoor unit heat exchanger 12 and an outdoor unit heat exchanger 13, the exhaust end of the compressor 11 communicates with the first end of the indoor unit heat exchanger 12, and the air conditioning system also Including: four-way valve 14 and heat storage module 15;

[0052] The first end a of the four-way valve 14 communicates with the exhaust end of the compressor 11, the second end b communicates with the first end of the thermal storage module 15, the third end c communicates with the suction end of the compressor 11, and the fourth end d communicates with the first end of the outdoor unit heat exchanger 13, when the air conditioning system needs to enter the normal heating mode, the...

Embodiment 2

[0058] This embodiment provides another uninterrupted heating air conditioning system, figure 2 It is a structural diagram of an air-conditioning system according to another embodiment of the present invention. In order to prevent the refrigerant in the heating system from entering into the compressor 11 after heat release, such as figure 2 As shown, on the basis of the above-mentioned embodiments, the air-conditioning system further includes: a gas-liquid separator 16, arranged between the third end c of the four-way valve 14 and the suction end of the compressor 11, for separating the four-way The third end c of the valve 14 discharges the gaseous and liquid refrigerants, collects the liquid refrigerants, and only allows the gaseous refrigerants to return to the compressor 11 .

[0059] After the gas-liquid separator 16 collects the liquid refrigerant, the amount of refrigerant flowing in the heating cycle system decreases. If it runs for a long time, the refrigerant parti...

Embodiment 3

[0063] This embodiment provides another uninterrupted heating air conditioning system, image 3 It is a structural diagram of an air-conditioning system according to yet another embodiment of the present invention, as image 3 As shown, on the basis of a conventional heat pump system, a first four-way valve 33 and a second four-way valve 34 are respectively provided at the exhaust port of the oil-gas separator 32 at the exhaust end of the compressor 31, wherein the first four-way valve 33 includes a first port a1, a second port b1, a third port c1, and a fourth port d1, and the second four-way valve 34 includes a first port a2, a second port b2, a third port c2, and a fourth port d2, respectively. The exhaust port of the oil-gas separator 32 communicates with the first port a1 of the first four-way valve 33 and the first port a2 of the second four-way valve 34 respectively. A heat storage module 35 is arranged between the second interfaces b1 of the 33 .

Abstract

The invention discloses an uninterrupted heating air conditioning system, a control method thereof and air conditioning equipment. The air conditioning system comprises a four-way valve and a heat accumulating module. The four-way valve is used for gaining electricity for the air conditioning system which needs to enter a normal heating mode, wherein the first end of the four-way valve and the second end of the four-way valve are connected and the fourth end of the four-way valve and the third end of the four-way valve are connected. The four-way valve is used for losing electricity for the air conditioning system which needs to enter a defrosting heating mode, wherein the first end of the four-way valve and the fourth end of the four-way valve are connected and the second end of the four-way valve and the third end of the four-way valve are connected. The heat accumulating module is used for connection in a direction from the second end of the heat accumulating module to the second end of a heat exchanger of an outdoor unit when the air conditioning system needs to enter the normal heating model to store heat and is used for connection in a direction from the second end of a heatexchanger of an indoor unit to the second end of the heat accumulating module when the air conditioning system needs to enter the defrosting heating mode so as to achieve heating circulation in the defrosting heating mode. According to the invention, uninterrupted heating when the heat exchanger of the outdoor unit defrosts can be achieved, so that the comfort of the air conditioning system is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system with continuous heating, a control method thereof, and air conditioning equipment. Background technique [0002] When the heat pump air conditioner is in heating operation, the heat exchanger of the outdoor unit acts as an evaporator, and the refrigerant flowing through it evaporates and absorbs heat, and the temperature is low. Frost, severe frost will affect the heat exchange effect of the outdoor heat exchanger. In a conventional air conditioning system, when it is detected that the outdoor heat exchanger is severely frosted, the unit switches the direction of the outdoor heat exchanger to the high-pressure side through the four-way valve for defrosting. But at this time, the heat exchanger of the indoor unit is in a cooling state, and the heat will be absorbed by evaporation, and the indoor temperature will drop, which will affect the comf...
