Connection；Can mechanically connect, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary,
Can be two connections of element internal.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning of the language in the utility model.
As shown in figure 1, a kind of air-conditioning system of the accumulation of heat defrost provided for the utility model, including refrigerant loop, institute
State refrigerant loop and be provided with compressor 1, indoor heat exchanger 4, throttling arrangement 5, outdoor heat exchanger 6 and for changing refrigerant
The reversal valve 2 of flow direction, it also includes being provided with heat-exchange tube 13, the heat-exchange tube 13 and institute in storage heater 3, the storage heater 3
Indoor heat exchanger 4 is stated to be arranged in parallel, and the heat-exchange tube 13 and the indoor heat exchanger 4 optionally access the system
Refrigerant circuit, it refers to that can be all connected with indoor heat exchanger 4 with heat-exchange tube 13 that refrigerant loop is optionally accessed herein
Enter refrigerant loop, it is also possible to which any one is independently accessed.
Wherein, the storage heater 3 includes insulation shell 12 and the heat-storing material 14 in the insulation shell 12, described
Heat-exchange tube 13 carries out heat exchange in the insulation shell 12 with the heat-storing material 14, in defrost, heat-exchange tube 13
Temperature reduction, heat-exchange tube 13 is heated by the heat release of heat-storing material 14.
The switching of pipeline for convenience, the two ends of the indoor heat exchanger 4 are provided with regulating valve 8,9；The heat-exchange tube 13
Two ends be provided with regulating valve 7,10, the regulating valve is preferably electronic valve, in order to automatically control.
Wherein, temperature sensor 11 is provided with the storage heater 3, the temperature for monitoring heat-storing material 14 in storage heater 3.
Wherein, the reversal valve 2 is preferably four-way reversing valve, simple structure, convenient control.
In addition, being using the control method of air-conditioning system described above：In refrigerant loop heating operation, that is, pass through
The high-temperature high-pressure refrigerant gas of the compression of compressor 1 sequentially passes through indoor heat exchanger 4, and throttling arrangement 5 and outdoor heat exchanger 6 are returned to
Compressor 1, the now heat release of indoor heat exchanger 4, heating indoor air；Now regulating valve is fully open, and heat-exchange tube 13 accesses system
Refrigerant circuit, the accumulation of heat of storage heater 3；
When defrost is needed, switch reversal valve 2, change the flow direction of refrigerant, indoor heat exchanger 4 breaks with refrigerant loop
Open, i.e., regulating valve 8,9 is closed, regulating valve 7,10 is opened, heat-exchange tube 13 is connected with refrigerant loop, compressed by compressor 1
High-temperature high-pressure refrigerant gas first pass through outdoor heat exchanger 6, carry out defrost to outdoor heat exchanger 6, the temperature of heat-exchange tube 13 drop
It is low, heat-exchange tube 13 is heated by the heat release of storage heater 3, the commutation of reversal valve 2 switches to heating mode after the completion of defrost.
Specifically, can set when outdoor heat exchanger 6 reaches the first design temperature T1 is for example higher than defrost temperature 0-5 degree
When, heat-exchange tube 13 accesses refrigerant loop, and so as to avoid storage heater 3 from being constantly in heat storage state, and storage heater 3 itself is also needed
Heat release is wanted, unnecessary energy waste is caused.
Wherein, in refrigerant loop heating operation, when the temperature T of the storage heater 3 reaches the second design temperature T2,
The storage heater 3 is disconnected and stops accumulation of heat, i.e. the unlatching of regulating valve 8,9, regulating valve 7,10 is closed；When the storage heater 3 temperature T not
When reaching the second design temperature T2, regulating valve 7,8,9,10 is opened simultaneously, and refrigerant simultaneously flows through indoor heat exchanger 4 and storage heater
3, the now accumulation of heat of storage heater 3；When heat-storing material 14 is phase-change material, the second design temperature T2 is phase transition temperature.
As can be seen from the above embodiments, the utility model is by setting the storage heater in parallel with indoor heat exchanger so that
Outdoor heat exchanger does not utilize Indoor Thermal amount in defrost, so as to improve the stabilization and human thermal comfort in indoor temperature field.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
