Preferably, the chamber 17 is closed except for the air inlet 171 and the air outlet 172.
Further, on the basis of the foregoing embodiment, the present embodiment further provides a refrigeration device of the air conditioner indoor unit 2, and as shown in fig. 4 and 5, the air conditioner indoor unit 2 further includes a box body 25, and the box body 25 is located in the ventilation duct of the air conditioner indoor unit 2. The ventilation air duct of the air conditioner indoor unit 2 refers to an air duct between an air inlet and an air outlet of the air conditioner indoor unit 2 and used for ventilation through a fan. A box 25 is arranged in the ventilation duct of the air conditioner 2 and is used for containing a temperature-regulating medium which is used for releasing cold or heat. For example, a user may place ice cubes in the case 25 and blow the fan to expel cool air to the kitchen environment to provide an energy efficient way of cooling. Alternatively, the user places hot water in the box 25 and discharges hot air to the kitchen environment under the blowing of the fan to provide an energy-saving heating mode.

On the other hand, when the air conditioning indoor unit 2 heats, no moisture exists between the box 25 and the water receiving tray 26, and the duct 18 is in a communicating state, so that the heat discharged from the first heat exchanger 12 in the chamber 17 can be sucked into the air conditioning indoor unit 2 in a negative pressure state of the air conditioning indoor unit 2 to heat the kitchen environment.
The water pan 26, the guide pipe 18 and the cavity 17 in the embodiment solve the discharging problem of the box 25 and the condensed water, and can conduct the heat discharged by the first heat exchanger 12 into the air conditioner indoor unit 2 when the air conditioner indoor unit 2 heats, so that the energy utilization rate is improved, the structure is simple, and the functions are diversified.

step S100, acquiring an indoor temperature Tr and an indoor set temperature Ts; specifically, the kitchen temperature is detected in real time by a temperature sensor provided on the indoor temperature Tr, and the set temperature of the air conditioner indoor unit is obtained.
Step 200, determining the absolute value of the temperature difference between the indoor temperature Tr and the indoor set temperature Ts; when the air conditioner indoor unit 2 operates in the cooling mode, the indoor temperature Tr is higher than the set temperature Ts of the air conditioner indoor unit, and the absolute value of the temperature difference takes the difference value between the indoor temperature Tr and the indoor set temperature Ts.
Step S300, controlling at least one of the opening value of the first valve body 24, the running frequency of the compressor 11, the set temperature of the refrigerator 1 freezer and the opening value of the second valve body 19 according to the absolute value of the temperature difference; wherein the opening value of the first valve body 24 increases with the increase of the absolute value of the temperature difference, the operation frequency of the compressor 11 increases with the increase of the absolute value of the temperature difference, the set temperature of the refrigerator 1 freezer decreases with the increase of the absolute value of the temperature difference, and the opening value of the second valve body 19 increases with the increase of the absolute value of the temperature difference.
Specifically, in the actual control process, for example, only the opening value of the first valve body 24 and the operating frequency of the compressor 11 are controlled according to the absolute value of the temperature difference, only the control instruction that the opening value of the first valve body 24 increases with the increase of the absolute value of the temperature difference and the operating frequency of the compressor 11 increases with the increase of the absolute value of the temperature difference are stored in the controller, and other instructions may not be stored. Or all are stored in a memory module of the controller, and corresponding control instructions are extracted for the adjusted parameters.
Specifically, at least one of the opening value of the first valve body 24, the operating frequency of the compressor 11, the set temperature of the refrigerator 1 and the opening value of the second valve body 19 may be controlled according to the absolute value of the temperature difference, and all the control is taken as an example in this embodiment.
Specifically, the present embodiment provides a specific embodiment of controlling the opening value of the first valve body 24, the operating frequency of the compressor 11, the set temperature of the refrigerator 1 and the opening value of the second valve body 19 according to the absolute value of the temperature difference.
