Fig. 5 is that the three use type earth source absorption type heat pumps that the utility model provides supply cold-peace domestic hot-water supply simultaneously, reclaim the schematic diagram that absorbs heat pattern, the water outlet of underground pipe 12 enters in condenser 9 through underground pipe pump 13 and the 6th valve 21, gets back to underground pipe 13 carry out heat extraction after absorption condensation heat through the 9th valve 24 and the 5th valve 20.Air-conditioning backwater enters in evaporimeter 9 and is cooled to required chilled water temperature through user's pump 15 and the 4th valve 19, then gets back to heating air conditioning user 14 from the first valve 16 and carries out cooling.The water outlet of domestic hot-water's case 34 enters recovery absorption heat in absorber 8 through the 14 valve 32 and domestic hot-water's pump 31, then gets back to domestic hot-water's case 34 through the 15 valve 35 and mixes with tap water supply, and constantly circulating-heating is to temperature required and hot water amount.
Fig. 6 is that the three use type earth source absorption type heat pumps that the utility model provides supply cold-peace domestic hot-water supply simultaneously, reclaim the schematic diagram that absorbs the solidifying heat pattern of hot and cold, different from pattern shown in Fig. 5, does not need to move underground pipe heat exchanging part in this pattern.The water outlet of domestic hot-water's case 34 first enters further heating absorber 8 from domestic hot-water's pump 31 again after the 12 valve 29 enters plate type heat exchanger 27 preheatings, then gets back to domestic hot-water's case 34.Under this pattern, condenser 9 and absorber 8 have been realized indirect series connection by plate type heat exchanger 27, and first recovering condensing heat, rear direct recovery absorb heat to domestic hot-water indirectly.The pattern hot with only reclaiming absorption contrasts, and do not adopt underground pipe water outlet as cooling water, and condensation temperature can be slightly high, the COP of heat pump can decrease, but absorb the solidifying heat of hot and cold owing to reclaiming simultaneously, domestic hot-water's heating capacity is larger, is suitable for the occasion that domestic hot-water's demand is large.
Fig. 7 is the schematic diagram of the simple cooling pattern of three use type earth source absorption type heat pumps that provides of the utility model, the water outlet of underground pipe 12 is introduced into condenser 9 absorption condensation heat after underground pipe pump 13 and the 6th valve 21, then enter plate type heat exchanger 27 and take away and absorb heat, then get back to and in underground pipe 13, carry out heat extraction through switchable pump the 28, the 11 valve 26 and the 5th valve 20.Under this pattern, condenser 9 and absorber 8 have been realized indirect series connection by plate type heat exchanger 27, and condensation heat is first directly taken away in underground pipe water outlet, rear indirectly taking away absorbs heat.This mode operation do not need domestic hot-water, only need cooling in, or also can be switched to this pattern from operational mode shown in Fig. 5, Fig. 6 in the time that domestic hot-water's case 34 is full.
