    Solar heat water-circulating pump (29) runs, solar water is entered the solar water deflector (5-4) of case wing formula low-temperature heat accumulating heat exchanger (33) by solar heat water-circulating pump (29), through solar water heat exchanger channels, low level solar thermal energy is passed to the organic phase-change accumulation of heat powder in heat storage tank (5-3), draw through solar water deflector (5-4) again, return to plate solar collector (32) be heated again, hot water in plate solar collector (32) is again introduced into solar heat water-circulating pump (29) afterwards, complete a solar water circulation;System passes through indoor fin tube type air heat exchanger (25) to user's heat supply, store Lowlevel thermal energy in heat storage tank (5-3) in case wing formula low-temperature heat accumulating heat exchanger (33) standby simultaneously, so far, the operation under unit completes solar energy auxiliary regenerator device heat supply mode.
  9. 9. the source pump operation method containing the case wing formula low-temperature heat accumulating heat exchanger described in claim 4, it is characterised in that: the operation method under air source heat pump heating mode is realized by following steps:
    Step one: open the first electromagnetic valve (E1), closes the 3rd electromagnetic valve (E3) and the 4th electromagnetic valve (E4);
    Step 2: system refrigerant circulation is:
    Cold-producing medium is R32, cold-producing medium through compressor (20) air vent enter electric four passes reversal valve (21) first lead to, indoor fin tube type air heat exchanger (25), forward check valve (23), the first electromagnetic valve (E1), capillary tube (24) and outside fin tube type air heat exchanger (22) is sequentially passed through afterwards by the threeway of electric four passes reversal valve (21), through the second logical and four-way of electric four passes reversal valve (21) after, flow successively through forward check valve (23) and gas-liquid separator (26) returns to compressor (20);System is by indoor fin tube type air heat exchanger (25) to user's heat supply, and so far, unit completes the operation under air source heat pump heating mode;
    Step 3: when system inner refrigerant circular flow is too low, opening the second electromagnetic valve (E2) and the 5th electromagnetic valve (E5), now part of refrigerant is front bypassed at electromagnetic valve (E1): cold-producing medium sequentially passes through the second electromagnetic valve (E2), capillary tube (24), flash evaporation (27) and the 5th electromagnetic valve (E5) and sprays into compressor (20) through steam nozzle (28);System by indoor fin tube type air heat exchanger (25) to user's heat supply, so far, the operation under air source heat pump heating mode when unit completion system inner refrigerant circular flow is too low.
  10. 10. the source pump operation method containing the case wing formula low-temperature heat accumulating heat exchanger described in claim 4, it is characterised in that: the operation method under thermophore defrosting mode is realized by following steps:
    Step one: open the 3rd electromagnetic valve (E3), close the first electromagnetic valve (E1), the second electromagnetic valve (E2), the 4th electromagnetic valve (E4) and the 5th electromagnetic valve (E5);
    Step 2: system refrigerant circulation is:
    Cold-producing medium is R32, cold-producing medium sequentially passes through the first of electric four passes reversal valve (21) through compressor (20) and leads to logical with second, pass sequentially through outside fin tube type air heat exchanger (22) afterwards, forward check valve (23), 3rd electromagnetic valve (E3), electric expansion valve (30) and restricting orifice (31) enter the cold-producing medium deflector (5-4) of case wing formula low-temperature heat accumulating heat exchanger (33), by refrigerant heat exchanger passage, the Lowlevel thermal energy being stored in heat storage tank (5-3) takes out, case wing formula low-temperature heat accumulating heat exchanger (33) is flowed out again through cold-producing medium deflector (5-4), finally sequentially pass through forward check valve (23) and gas-liquid separator (26) returns to compressor (20);System utilizes the Lowlevel thermal energy defrosting being stored in case wing formula low-temperature heat accumulating heat exchanger (33), and so far, unit completes the operation under thermophore defrosting mode.
