System has 3 kinds of operational modes, as shown in Fig. 7,8,9.
When Fig. 7 is fresh air dehumidification, new wind first dehumidifies, then through double reheat.
Fig. 8 is new wind when not dehumidifying, and by accessory system 400 heat-obtaining hot water preparing, the first valve 1, the 6th valve 10 are closed, and the second valve 4, the 7th valve 11 are opened, and motor-driven valve 5 cuts out.Entered in auxiliary gas-liquid heat-exchange 401 by the cryogenic freezing water (frozen liq) of absorbing and cooling temperature in the first evaporimeter 201, absorption chamber outer air heat gets back to the first evaporimeter 201 after heating up.
The high-temperature-hot-water heated up that absorbs heat in the first condenser 202 enters storage in boiler 300, provides domestic hot-water.
Native system and system shown in Figure 5 cenotype ratio, add accessory system 400, produce domestic hot-water when both can ensure fresh air dehumidification, can not need to produce domestic hot-water separately during dehumidifying at new wind again, ensure the hot water supply whole year.
Fig. 9 is when new wind does not dehumidify, and by accessory system 400 heat-obtaining hot water preparing, and utilizes the new wind of hot water heating simultaneously, and the first valve 1, the 6th valve 10 are closed, and the second valve 4, the 7th valve 11 are opened, motor-driven valve 5 is opened.In evaporimeter 201, entered auxiliary gas-liquid heat-exchange 401 by the cryogenic freezing water (frozen liq) of absorbing and cooling temperature, absorption chamber outer air heat gets back to the first evaporimeter 201 after heating up.
Compared with Fig. 8, add the function of the new wind of hot water heating, in the winter time and the new wind of transition season hot water heating ensure the relative humidity of new wind, namely the 3rd valve 5 is opened, 3rd pump 6 drives hot water through the second gas-liquid heat-exchange 103, circulates in loop W1, utilizes the new wind of hot water heating produced.
Figure 10 adopts hot water reheating after fresh air dehumidification, simultaneously hot water preparing system diagram.
Compared with Fig. 1 unlike from evaporimeter 201 out after chilled water (cold liquid) enter the first gas-liquid heat-exchange 101, directly get back to evaporimeter 201 by after fresh air dehumidification, and new wind is by hot water heating.That is: motor-driven valve 5 is opened, and utilizes the new wind of hot water heating produced, to obtain suitable wind pushing temperature and relative humidity.
Figure 11 adopts hot water reheating after fresh air dehumidification, simultaneously hot water preparing, and with accessory system 400.
Native system comparatively Figure 10 system adds 400 off-premises stations, and corresponding chilled water pipeline, is switched by motor-driven valve and fresh air handining unit water lines.
Native system has 3 kinds of operational modes, as shown in Figure 12,13,14.
When Figure 12 is fresh air dehumidification, new wind first dehumidifies, then through superheated water reheating.
Figure 13 is new wind when not dehumidifying, and by accessory system 400 heat-obtaining hot water preparing, the first valve 1, the 6th valve 10 are closed, and the second valve 4, the 7th valve 11 are opened, and motor-driven valve 5 cuts out.Entered in auxiliary gas-liquid heat-exchange 401 by the cryogenic freezing water (frozen liq) of absorbing and cooling temperature in the first evaporimeter 201, absorption chamber outer air heat gets back to the first evaporimeter 201 after heating up.
The high-temperature-hot-water heated up that absorbs heat in the first condenser 202 enters storage in boiler 300, provides domestic hot-water.
Figure 14 is when new wind does not dehumidify, and by accessory system 400 heat-obtaining hot water preparing, and utilizes the new wind of hot water heating simultaneously, and the first valve 1, the 6th valve 10 are closed, and the second valve 4, the 7th valve 11 are opened, motor-driven valve 5 is opened.In the first evaporimeter 201, entered auxiliary gas-liquid heat-exchange 401 by the cryogenic freezing water (frozen liq) of absorbing and cooling temperature, absorption chamber outer air heat gets back to the first evaporimeter 201 after heating up.
Figure 15 and Fig. 2 is not uniquely both, and the heat pump 200 in Figure 15 have employed two compression systems
Namely a heat pump circulating system is added, and corresponding refrigerant pipeline, containing 201,205 two evaporator series, 202,206 two condensers series connection.
Native system is run respectively by two refrigerant loops, chilled water is through double effect evaporator series connection cooling, and condensed water is connected by condensed in two stages device and heated up, and the system evaporation temperature difference and the condensation temperature difference increase, refrigerating efficiency and heating efficiency improve, and refrigerating capacity and heating capacity be comparatively Fig. 2 increase also.
Figure 16 changes on the basis of Fig. 6, namely increases communicating pipe, and the 4th valve 7, and increases water pump 14 on the loop C2 of accessory system 400, when motor-driven valve 7 is opened, after motor-driven valve 4 cuts out, forms close loop, provides power by water pump 14.Add heat exchanger 9 simultaneously, and corresponding hot water line and valve 12 and 13.Hot water side is entered by hot water storage tank's water outlet, and after heat exchange, water tank is got back in cooling.
Figure 16 system except possessing the function of Fig. 6 system, can also hot water in boiler 300 excessive time, utilize accessory system 400 outwards to dispel the heat.Hot water enters heat exchanger 9, and the water circulated with accessory system carries out heat exchange, is improved by its coolant-temperature gage, and the hot water after cooling gets back to boiler 300.Like this, the unnecessary heat spreader of hot water to accessory system recirculated water, accessory system 400 by heat loss to outdoor air.
Figure 17 is the another kind of operational mode of Figure 16, when namely fresh air handining unit does not need air dewetting, as winter, utilizes accessory system 400 hot water preparing, defrosts with hot water to auxiliary gas-liquid heat-exchange 401 simultaneously.
When needs defrost, the first valve 1, the 6th valve 10 are closed, and the second valve 4, the 7th valve 11 are opened, and the 3rd valve 5 cuts out, and the 4th valve 7 cuts out, and the 5th valve 8 is opened, and the 8th valve 12 cuts out, and the 9th valve 13 is opened, as Figure 19.The hot water of hot water is driven into heat exchanger 9 by the 3rd pump 6; heating comes in flash-pot 201 by the cryogenic freezing liquid of absorbing and cooling temperature; carry out the frozen liq after heat exchange intensification and enter auxiliary gas-liquid heat-exchange 401 again; it is defrosted; frozen liq through auxiliary gas-liquid heat-exchange 401 enters the first evaporimeter 201 again; so can realize the continuous hot water preparing of heat pump, and without the need to shutting down.
Eliminate the 4th pump 14 in Figure 17, frozen liq is driven by the first pump 2.
When not needing defrosting, the 3rd pump 6 stops, or in order to prevent hot water in pipeline from freezing, low cruise.
The high-temperature-hot-water heated up that absorbs heat in condenser 202 enters in hot water and stores, and provides domestic hot-water.
When utilizing heat pump to produce domestic hot-water in the winter time by native system, use tank hot water to be promoted by off-premises station inflow temperature, effectively can solve off-premises station frosting problem; avoid compressor emergency shutdown; heat pump efficiency is improved simultaneously, and system operation time is longer, more stable.
