Two, background technology
Along with the raising of people's living standard, the use of air-conditioning is more and more universal, and traditional air-cooled air conditioner unit is able to broad development, but the air-cooled air conditioner unit is subjected to the influence of outdoor environment temperature bigger when operation, and unit eer is lower, and power consumption is big.The water-ring air conditioner group is to realize the air-conditioning system of refrigerating operaton by water source radiating modes such as cooling towers, and it compares the Energy Efficiency Ratio height with air-cooled unit, and power consumption is few, and is more energy-conservation more than 35% than air cooling system generally speaking.Therefore the water ring air-conditioning has obtained development rapidly, and its application has been not limited to large-scale central air conditioner system, and has also obtained extensive use in some middle and small air conditioning systems.
In the water ring air-conditioning system, heat reclamation device is installed, is utilized the more existing researchs of heat supply domestic hot-water of reclaiming.Heat reclamation device is installed on the fluorine pipeline between compressor and the condenser, and this mode can obtain the recuperation of heat effect, but the systematic comparison complexity when the temperature that reclaims hot water is higher, tends to cause problems such as compressor current increase, Energy Efficiency Ratio reduction.Just be based on the problems referred to above, proposing to connect on the cooling water pipeline in the water ring air-conditioning system water water-to-water heat exchanger and reclaimed heat, thereby reached the purpose that the domestic hot-water is provided.
Three, summary of the invention
The purpose of this utility model provides a kind ofly both can freeze, and domestic hot-water's novel energy-conserving water ring air-conditioning system can be provided by recuperation of heat in refrigeration again.
Basic design of the present utility model is made up of water-ring air conditioner, heat reclamation device and cooling system.Be connected heat reclamation device and control valve between the coolant outlet of water-ring air conditioner and the import of cooling tower, be connected cooling water pump between cooling water inlet and the cooling tower outlet; Recuperation of heat pipeline one end of heat reclamation device connects the water inlet of water storage tank, and the other end is connected with the delivery port of water storage tank through water pump, magnetic valve; On the water storage tank water pipe water compensating valve is housed, on domestic hot-water's pipeline valve is housed.
The throttling arrangement of water-ring air conditioner is expansion valve or capillary; Evaporimeter is double pipe heat exchanger, shell and tube exchanger or plate type heat exchanger.
The utility model has following result of use:
1 utilizes the heat energy heating domestic water that reclaims, good energy-conserving effect in refrigeration.
2 heat domestic water when low power consumption utilizes the water ring air conditioner refrigerating, storage power is saved electricity charge spending, reasonable energy utilization.

Five, the specific embodiment
It is as follows to narrate implementation process in conjunction with the accompanying drawings, as shown in Figure 1:
Embodiment 1:
When the utility model refrigerating operaton and when reclaiming heat, it is installed in place, connect pipeline, connect power supply, open water compensating valve 2-1 and give water storage tank 2-2 topped up with water, rotating temperature controlled device 2-3 sets the temperature of water.Start water-ring air conditioner 1, heat reclamation device 2 and cooling system 3, chilled water pump 1-5, cooling water pump 3-3, water pump 2-6 and compressor 1-1 operation, magnetic valve 2-5 opens automatically.The refrigerant gas that compressor 1-1 discharges HTHP is condensed into liquid through condenser 1-2, again through throttling arrangement 1-3 step-down throttling to evaporimeter 1-4, get back to compressor refrigerant liquid is evaporated to gas in evaporimeter 1-4 after and continue circulation.When passing through condenser 1-2, the refrigerant gas of HTHP the temperature of cooling water is raise because heat is emitted in condensation, owing to evaporation absorbs heat the temperature of chilled water is reduced during refrigerant liquid process evaporimeter 1-4, temperature reduces the low chilled water process chilled water pump 1-5 in back to fan coil 1-6, by fan coil 1-6 cold is sent into indoorly, reached the purpose of indoor refrigeration; Hot water after simultaneously the cooling water side temperature raises through water water-to-water heat exchanger 2-7, control valve 3-2 to cooling tower 3-1, get back to condenser 1-2 through cooling water pump 3-3 then and continue circulation, emit heat during hot water process water water-to-water heat exchanger 2-7, and the water in the water storage tank 2-2 absorbs heat when magnetic valve 2-5, water pump 2-6 enter water water-to-water heat exchanger 2-7, hot water behind the absorption heat is got back to water storage tank 2-2, so the water temperature of circulation in water storage tank 2-2 reaches the temperature that temperature controller 2-3 sets, when temperature reaches, magnetic valve 2-5 closes, and water pump 2-6 is out of service.When the needs domestic hot-water, opening valve 2-4 can use, running water is given water storage tank 2-2 moisturizing automatically through water compensating valve 2-1, if need to adjust the temperature of water in the water storage tank 2-2, then adjust control valve 3-1 and discharge is increased or reduce get final product, so just reached the purpose that the recovery heat provides the domestic hot-water.In addition, proceed exchange heat when passing through the cooling water process cooling tower 3-1 after water water-to-water heat exchanger 2-7 carries out exchange heat, get back to condenser 1-2 through cooling water pump 3-3 then and continue circulation.
Embodiment 2:
When the utility model refrigerating operaton does not reclaim heat, it is installed in place, connect pipeline, connect power supply.Start water-ring air conditioner 1, cooling system 3, chilled water pump 1-5, cooling water pump 3-3 and compressor 1-1 operation, magnetic valve 2-5 is in closed condition, and water pump 2-6 does not move.The refrigerant gas that compressor 1-1 discharges HTHP is condensed into liquid through condenser 1-2, again through throttling arrangement 1-3 step-down throttling to evaporimeter 1-4, evaporation absorbs and gets back to compressor behind the heat and continue circulation in evaporimeter 1-4.Emitting heat when the refrigerant gas of HTHP passes through condenser 1-2 raises the temperature of cooling water, the higher water of temperature through water water-to-water heat exchanger 2-7, control valve 3-2 to cooling tower 3-1, hot water is emitted the heat temperature and is reduced in cooling tower 3-1, get back to condenser 1-2 through cooling water pump 3-3 then and continue circulation.Refrigerant liquid absorbs heat during through evaporimeter 1-4 reduces the temperature of chilled water, and the chilled water after temperature reduces to fan coil 1-6, is sent into cold by fan coil 1-6 indoorly through chilled water pump 1-5, reaches the purpose of indoor refrigeration.
