Ground, reversing unit 4 can be four-way reversing valve, but not limited to this.
After refrigerant enters phase-change thermal storage heat exchanger 1, it can exchange heat with the phase change medium in phase-change thermal storage heat exchanger 1, phase
The storage and release of heat are realized after change medium neither endothermic nor exothermic by the change of itself phase, and refrigerant is in phase-change thermal storage
Without carrying out heat exchange with environment after heat exchange in heat exchanger 1, this makes air conditioner in refrigeration without to Environment release heat,
Without absorbing heat from environment when heating, and then the integral structure of air conditioner may be implemented, has broken conventional air conditioner fission
The routine of formula structure.
It exchanges heat when refrigerant flows through First Heat Exchanger 31 with air, achievees the purpose that refrigeration or heating.
Second heat exchanger 32 is mounted in water tank 33, and the second heat exchanger 32 and water tank 33 can form water cooling heat exchanger, system
It exchanges heat when cryogen flows through the second heat exchanger 32 with water, water tank 33 is allowed to provide hot water.Preferably, water tank 33 is used for
Hot-water supply, such as water tank 33 can be equipped with inlet and outlet, and cold water flows into from water inlet and carrying out hot friendship with refrigerant
It is flowed out after changing from water outlet, the hot water produced can be used for washing the dishes, have a bath, heat.The water pipe line of spouse's water tank 33 is set
Meter, the air-conditioning system is more suitable for kitchen ceiling mounting type or Embedded air conditioner structure.
The refrigerant circulation loop of air-conditioning system is described below with reference to Fig. 1.
Specifically, when air-conditioning system, which is run, freezes, the heat exchange branch where First Heat Exchanger 31 is connected to, the second heat exchanger
Heat exchange branch where 32 disconnects, and the first interface 41 of reversing unit 4 is connected to the 4th interface 44, third interface 43 and second
Interface 42 is connected to.Refrigerant successively pass through the exhaust outlet 22 of compressor 2, the first interface 41 of reversing unit 4, the 4th interface 44,
Phase-change thermal storage heat exchanger 1, first throttle element 63, First Heat Exchanger 31,4 second interface 42 of reversing unit, third interface 43, most
Compressor 2 is returned to from the air entry 21 of compressor 2 afterwards, is so recycled.First Heat Exchanger 31 is evaporator at this time, and phase-change thermal storage changes
Hot device 1 is condenser.Refrigerant exchanges heat when flowing through phase-change thermal storage heat exchanger 1 with phase change medium, what refrigerant was released
Heat is absorbed and is stored by phase change medium, and the state of phase change medium changes, such as can be liquid by Solid State Transformation.
It exchanges heat when refrigerant flows through First Heat Exchanger 31 with air, absorbs the heat in air, refrigeration is achieved the purpose that with this.
Wherein, during air-conditioning device runs and freezes, since phase change medium absorbs and stores condensation heat, state
It is liquid by Solid State Transformation.When phase change medium is completely reformed into liquid, heat storage capacity reaches the upper limit, and air-conditioning device is not at this time
Can continue to freeze, air-conditioning device need to start the first regenerative process make phase change medium restore heat storage capacity, certainly, phase change medium not
When being fully converted to liquid, if completing to cook, the first regenerative process can also be started, so that the accumulation of heat energy of phase-change thermal storage heat exchanger 1
Power reaches maximum.The process charges similar to battery, and phase change medium can be made to be completely reformed into solid-state by liquid in a short time, weight
The new ability for restoring heat accumulation, such air-conditioning device can continue to freeze.
The implementation of the first regenerative process of phase change medium is starting air-conditioning dress after the refrigeration cycle for stopping air-conditioning device
The first reheat vapor cycle set, the heat exchange branch where First Heat Exchanger 31 disconnect, and the heat exchange branch where the second heat exchanger 32 connects
It is logical, the switching to refrigerant flow direction, the first interface 41 and second interface 42 of reversing unit 4 may be implemented by reversing unit 4
Connection, third interface 43 are connected to the 4th interface 44.Refrigerant successively passes through the exhaust outlet 22 of compressor 2, commutation during this
The first interface 41 of unit 4, the second heat exchanger 32, the second restricting element 66, phase-change thermal storage heat exchanger 1, changes at second interface 42
To the 4th interface 44, the third interface 43 of unit 4, compressor 2 finally is returned to from the air entry 21 of compressor 2, is so recycled.This
When phase transformation heat storage exchanger 1 be evaporator, the second heat exchanger 32 is condenser.Refrigerant when flowing through phase-change thermal storage heat exchanger 1,
It exchanging heat with phase change medium, the state of the heat stored in refrigerant suction phase change medium, phase change medium changes, such as
Solid-state is changed by liquid.Water when refrigerant flows through the second heat exchanger 32 and in water tank 33 exchanges heat, and heat is discharged into water
Amount, achievees the purpose that hot water preparing with this.While phase-change material energy storage characteristic can be made full use of in this way, energy benefit is improved
With rate, it is more energy-saving and environmentally friendly.
It should be noted that the air-conditioning system is more suitable for hot water preparing under summer operating mode, it is relatively more suitable for free-standing kitchen
Room.Because of free-standing kitchen relative closure, room temperature usually in winter can meet human body requirements substantially, therefore can save last winter
Season air conditioner heating system.
