Abstract
The invention discloses a central air conditioning system using a cooling water tank. The central air conditioning system consists of a cooling tower, a central air conditioning unit, the cooling water tank, a cooling circulating pump, a water source heat pump hot water unit, a heat pump water source circulating pump, a hot water storage tank, a heat pump heating circulation pump and a bypass valve, wherein a water outlet of the cooling water tank is connected to a water inlet of an evaporator of the central air conditioning unit through the cooling circulating water pump; a water outlet of the evaporator of the central air conditioning unit is connected with a water inlet of the cooling tower; a water outlet of the cooling tower is connected to a water inlet of the cooling water tank. According to the central air conditioning system using the cooling water tank, heat in the evaporator of a refrigerating unit is led to the cooling water tank for cooling, the heat produced by the evaporator when the air conditioning unit is used for refrigeration can be transferred to the cooling water tank, warm water in the cooling water tank is taken as a water source of the water source heat pump unit by the system, bath hot water is prepared by the water source water pump unit, the energy consumption for preparing the hot water can be greatly reduced, the hot water requirements of nearby hotels and residential areas can be met, and an obvious energy-saving effect is realized.
Description
Technical field
The present invention relates to a kind of central air conditioner system, particularly a kind of central air conditioner system of using cooling water tank.Use the present invention and routine to use the central air conditioner system of cooling tower to compare, can reduce the operation energy consumption of system, reduce operating cost.
Background technology
Conventional water cooled central air conditioner system, must use cooling water to be compressed to condenser to refrigerant after the generation heat carry out cooling.In order to distribute the heat of condenser, air-conditioning system is provided with water circulating pump and cooling tower usually, and water circulating pump is connected with cooling tower with condenser.During operation, the heat that water circulating pump just can produce refrigeration compressor discharged to atmosphere, reduces the temperature of refrigerant in condenser by cooling tower, guarantees that the air-conditioning unit normally freezes.
Because the heat of conventional water cooled central air conditioner system condensing device is to press to cooling tower discharged to atmosphere by water circulating pump, the waste that the heat produced during air-conditioning unit refrigeration will be in vain.
Adopt the central air conditioner system of cooling water tank, can be cooling by carrying out in the heat of the evaporimeter of refrigeration unit introducing cooling water tank, the heat produced during air-conditioning unit refrigeration just can be transferred in cooling water tank, and these heats just can be recycled.For example utilize the warm water in cooling water tank to prepare bath hot water by water source heat pump units, the energy consumption for preparing hot water just can descend greatly.Near the hot water of preparation can meet, the hot water demand of hotel and residence district, have significant energy-saving effect.
Through retrieval, in existing central air conditioner system, also do not use the invention of cooling water tank cooling air conditioning group evaporimeter.
Summary of the invention
The purpose of this invention is to provide a kind of central air conditioner system of using cooling water tank, system is provided with cooling water tank, and the water of cooling water tank is connected to cooling tower be connected to the evaporimeter of refrigeration unit by water circulating pump after, and then returns to cooling water tank.The heat produced in evaporimeter during air-conditioning unit refrigeration just can be transferred in cooling water tank.Warm water in cooling water tank can also be as the water source of water source heat pump units, and the watering source pump prepares hot water, deposits in the hot water water storage box interior for the user.
The objective of the invention is to realize by the following method:
" a kind of central air conditioner system of using cooling water tank ", it comprises cooling tower, central air-conditioning unit, coolant circulation pump, the source heat pump water heater group, heat pump water source circulating pump, the hot water water storage box, the heat pump circulating pump, it is characterized in that: this central air conditioner system has cooling water tank, the delivery port of cooling water tank is connected to the water inlet of central air-conditioning unit evaporimeter by water circulating pump, the delivery port of central air-conditioning unit evaporimeter is connected to the water inlet of cooling tower, and the delivery port of cooling tower is connected to the water inlet of cooling water tank.
Between the intake-outlet of cooling tower, by-passing valve is housed, between the intake-outlet of cooling water tank, by-passing valve is housed.
The heat produced in evaporimeter while using air-conditioning unit refrigeration of the present invention just can be transferred in cooling water tank.By-passing valve all is housed between the intake-outlet of cooling tower and between the intake-outlet of cooling water tank, the cooling water of A/C evaporator can be circulated by cooling water tank separately, also can by cooling tower, be circulated separately, can also be by being circulated by cooling tower again after cooling water tank.
Warm water in cooling water tank can also be as the water source of water source heat pump units, and the watering source pump prepares hot water, deposits in the hot water water storage box interior for the user.Prepare bath hot water by water source heat pump units, the energy consumption for preparing hot water just can descend greatly, and near can meeting, the hot water demand of hotel and residence district, have significant energy-saving effect.
In practical engineering application embodiment, cooling water tank can utilize existing fire water box, can not increase construction costs.
The accompanying drawing explanation
Fig. 1 is the embodiments of the invention schematic diagram.
The specific embodiment
1 embodiment is for a more detailed description to the present invention by reference to the accompanying drawings:
" a kind of central air conditioner system of using cooling water tank " is by cooling tower 1, central air-conditioning unit 2, cooling water tank 3, coolant circulation pump 4, source heat pump water heater group 5, heat pump water source circulating pump 6, hot water water storage box 7, heat pump circulating pump 8, by-passing valve 9,10 forms.The delivery port of cooling water tank 3 is connected to the evaporimeter water inlet of central air-conditioning unit 2 by cooling circulating water pump 4, the evaporimeter delivery port of central air-conditioning unit 2 is connected to the water inlet of cooling tower 1, and the delivery port of cooling tower 1 is connected to the water inlet of cooling water tank 3.By-passing valve 9 is housed between the intake-outlet of cooling tower 1, by-passing valve 10 is housed between the intake-outlet of cooling water tank 3.
Operation principle of the present invention is as follows:
During system works
,If by-passing valve 9 is opened, by-passing valve 10 cuts out, and the water of cooling water tank 3 just is sent to the evaporimeter of central air-conditioning unit 2 by coolant circulation pump 4, then returns to cooling water tank 3, by the transfer of heat of central air-conditioning unit 2 evaporimeters in cooling water tank.If by-passing valve 9 cuts out, by-passing valve 10 is opened, and the recirculated water of being carried by coolant circulation pump 4 is without cooling water tank 3, and circulation between the direct evaporimeter at central air-conditioning 2 and cooling tower 1, be sent to unnecessary heat in air.If by-passing valve 9 all cuts out with by-passing valve 10, the cold water of cool cycles is circulated by cooling water tank and cooling tower.Source heat pump water heater group 5 utilizes the water of cooling water tank 3 as water source, prepares hot water and is sent in hot water water storage box 7, for the user.
