In addition, fin 132 excessively can intensively reduce the filling space of energy-accumulating medium, lead to the Mass lost of energy-accumulating medium, In addition the heat exchange amount in the unit time is excessive, and the energy-accumulating medium quality held just cannot maintain required heat-exchange time.Therefore, The design of 132 spacing of fin need to consider that corrresponding quality can be filled in heat exchange amount and required time section in the unit time simultaneously The two factors of energy-accumulating medium, so that the heat exchange amount and actually required heat exchange amount of fin-tube heat exchanger 13 are balanced, so that air-conditioning The internal structure design of system is more reasonable.

In one embodiment, as Figure 2-Figure 5, heat exchanger tube 131 is single row type, and single row type heat exchanger tube 131 is suitable for Ceiling mounting type air conditioner used in kitchen, horizontal direction length and width dimensions are larger, and vertical direction thickness is smaller, and heat exchanger tube 131 can be along level Direction is sprawled, and structure is relatively easy, easy for installation.

In another embodiment, as Figure 6-Figure 7, heat exchanger tube 131 is multi-row-type, for example, multi-row-type heat exchanger tube 131 For two rows of formula heat exchanger tubes 131, two rows of formula heat exchanger tubes 131 are identical as 132 spacing of fin of single row type heat exchanger tube 131, and two rows of formulas are changed Between heat pipe 131 by the way of cross arrangement, exchange heat it is more abundant, sequentially connected three heat exchanger tubes 131 of front two rows it Between distance of center circle it is equal, be 2-3 times of caliber.

The thickness of two rows of formula heat exchanger tubes 131 is also smaller, ceiling mounting type air conditioner used in kitchen is equally more suited to, certainly according to reality Border service condition, it can also be used to embedded and wall-hanging air conditioner.

In specific application, fin-tube heat exchanger 13 can be designed as multiple rows of structure, fin according to actual use occasion The using flexible of pipe heat exchanger 13 is strong.

As shown in Figure 1, packaging container 11 includes: shell 111, upper cover 112.

Wherein, as shown in figure 13, first interface 41 can be changed with one of them in second interface 42 and the 4th interface 44 To connection, third interface 43 can commutate with another in second interface 42 and the 4th interface 44 and be connected.It is connect for example, working as first When mouth 41 is connected to second interface 42, third interface 43 is connected to the 4th interface 44；When first interface 41 and the 4th interface 44 connect When logical, third interface 43 is connected to second interface 42.Thus, it is possible to cut air conditioner between refrigeration mode and heating mode It changes.Reversing unit 4 can be four-way valve or switch the combination with valve to realize commutation function

Specifically, as shown in figure 13, when air conditioner, which is run, to freeze, the first interface 41 and the 4th interface of reversing unit 4 44 connections, third interface 43 are connected to second interface 42.Refrigerant successively passes through the exhaust outlet 22 of compressor 2, reversing unit 4 First interface 41, the 4th interface 44, fin-tube heat exchanger 13, throttling set, First Heat Exchanger 31, reversing unit 4 second connect Mouth 42, third interface 43, finally return to compressor 2 from the air entry 21 of compressor 2, so recycle.First Heat Exchanger 31 at this time For evaporator, fin-tube heat exchanger 13 is condenser.Refrigerant when flowing through fin-tube heat exchanger 13, with energy-accumulating medium into Row heat exchange, the heat that refrigerant is released are absorbed and are stored by energy-accumulating medium, and the state of energy-accumulating medium changes, such as can Using by Solid State Transformation as liquid.It exchanges heat when refrigerant flows through First Heat Exchanger 31 with air, absorbs the heat in air, Achieve the purpose that refrigeration with this.

When air conditioner, which is run, to be heated, as shown in figure 13, may be implemented to cut refrigerant flow direction by reversing unit 4 It changes, the first interface 41 of reversing unit 4 is connected to second interface 42, and third interface 43 is connected to the 4th interface 44.During being somebody's turn to do Refrigerant successively passes through the exhaust outlet 22 of compressor 2, the first interface 41 of reversing unit 4, second interface 42, First Heat Exchanger 31, the 4th interface 44, the third interface 43 of throttling set, fin-tube heat exchanger 13, reversing unit 4, finally from compressor 2 Air entry 21 returns to compressor 2, so recycles.Fin-tube heat exchanger 13 is evaporator at this time, and First Heat Exchanger 31 is condensation Device.Refrigerant exchanges heat when flowing through fin-tube heat exchanger 13 with energy-accumulating medium, stores in refrigerant suction energy-accumulating medium Heat, the state of energy-accumulating medium changes, such as is changed into solid-state by liquid.When refrigerant flows through First Heat Exchanger 31, It exchanges heat with air, heat is discharged into air, heating is achieved the purpose that with this.

Wherein, during air-conditioning device runs and freezes, since energy-accumulating medium absorbs and stores condensation heat, state It is liquid by Solid State Transformation.When energy-accumulating medium is completely reformed into liquid, heat storage capacity reaches the upper limit, and air-conditioning device is not at this time It can continue to freeze, air-conditioning device, which need to start the first regenerative process, makes energy-accumulating medium restore heat storage capacity.The process is similar to battery Charging, can make energy-accumulating medium be completely reformed into solid-state by liquid in a short time, restore the ability of heat accumulation, such air-conditioning dress again Setting can continue to freeze.The implementation of the first regenerative process of energy-accumulating medium is starting after the refrigeration cycle for stopping air-conditioning device The heating of air-conditioning device recycles, and the heat for storing refrigerant suction energy-accumulating medium, energy-accumulating medium is changed into solid-state by liquid, extensive Multiple heat storage capacity.The regenerative process can the starting when air-conditioning device does not need refrigeration, such as can start in the period at night.By It can be sent into hot wind in the first regenerative process, therefore the door and window that the space where air conditioner is connected to interior need to be closed, avoid Heat enters the room other spaces.For example the window that the space is connected to outdoor is openable, so as to air circulation, outdoor air is same When heat in the space can be taken away.Certainly, when air conditioner is portable air-conditioning, the above process can be placed on outdoor progress, to keep away The hot wind for exempting from air conditioner blowout impacts indoor air conditions.

Likewise, during air-conditioning device runs and heats, since refrigerant absorbs heat, energy storage from energy-accumulating medium Medium is changed into solid-state by liquid.When energy-accumulating medium is completely reformed into solid-state, emission capacity reaches the upper limit, at this time air-conditioning system System component cannot continue to heat, and air-conditioning system component, which need to start the second regenerative process, makes energy-accumulating medium restore exothermic ability.It should Second regenerative process and above-mentioned first regenerative process are on the contrary, can make energy-accumulating medium be completely reformed into liquid by solid-state in a short time State, restores exothermic ability again, and such air-conditioning device can continue to heat.Its implementation is the system for stopping air-conditioning device Thermal cycle starts air-conditioning device refrigeration cycle, and energy-accumulating medium absorbs and store condensation heat during being somebody's turn to do, and is liquid by Solid State Transformation Thus state restores emission capacity.The second regenerative process usually starting when air-conditioning device does not need heating.Due to the second regeneration It can be sent into cold wind in the process, therefore the door and window that the space where air conditioner is connected to interior need to be closed, cold wind is avoided to enter room Other interior spaces.The window that space where air conditioner is connected to outdoor is openable, so as to air circulation.Certainly, air conditioner is When portable air-conditioning, the above process can be placed on outdoor progress, and the cold wind to avoid air conditioner blowout causes indoor air conditions It influences.

As a result, by setting reversing unit 4, switch the mode of air conditioner with can be convenient, so as to lead to as needed It crosses air conditioner and cooling capacity or heat is provided.Meanwhile regeneration function can be realized by switching the mode of air conditioner, make energy-accumulating medium weight It is new to restore heat accumulation and exothermic ability.
