Described room conditioning end-equipment can be air-conditioning box and fan coil.
Compared with prior art the utlity model has following characteristics and beneficial effect:
Sealed cooling tower of the present utility model, magnetic valve, open-type cooling tower, water pump, heat storage water tank etc. are formed the refrigeration heat recovery system, control operation by the PLC switch board, both can supply the low-temperature receiver of the cold air-conditioning of building, the free used heat that can utilize compressor to discharge again provides the hot water of the life about 60 ℃, is applicable to that hotel, restaurant, bathroom, hospital, swimming pool etc. need the building with cold air conditioner and domestic hot-water.
This unit main feature is to utilize outdoor sealed cooling tower that refrigeration system is carried out thermal balance to regulate, when the room conditioning temperature reaches setting value, and the hot water temperature is not when reaching 55～60 ℃, utilize outdoor sealed cooling tower to put enfleurage heat and carry out the thermal balance adjusting, remedy the deficiency of indoor caloric receptivity, continuation is warmed to setting value with the domestic water in the heat storage water tank, satisfies user's needs.
The utility model is controlled by the PLC switch board and is installed in outdoor sealed cooling tower, make it to open, make chilled water put the hot heat exchange of enfleurage outdoor with atmosphere by sealed cooling tower, suck the heat in the atmosphere, the used heat of compressor discharge simultaneously continues heating life hot water, when domestic water reaches setting value too, just can stop unit operation, satisfy the requirement that unit operation reaches two desired temperatures simultaneously.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is a system schematic of the present utility model.
Reference numeral: 1-compressor, 2-heat recovering heat exchanger, 3-evaporimeter, 4-condenser, 5-air temperature sensor, 6-air-conditioning box, 7-fan coil, 8-sealed cooling tower, 9-magnetic valve, 10-air-conditioning water pump, 11-open-type cooling tower, 12-cooling water pump, 13-recuperation of heat water pump, 14-hot water temperature sensor, 15-heat storage water tank, 16-hot water tap, 17-heat-exchanger pump, 18-PLC switch board, 19-circulating pump.
The specific embodiment
Embodiment is referring to shown in Figure 1, this water cooled refrigeration recuperation of heat unit thermal balance equipment, comprise by compressor 1, evaporimeter 3, condenser 4, medium circulation pipeline 22, heat recovering heat exchanger 2, life hot-water line 20, the water cooled refrigeration recuperation of heat unit that chilled water pipeline 21 is formed, the mouth of a river of heat recovering heat exchanger 2 is communicated with heat storage water tank 15 with hot-water line 20 and recuperation of heat water pump 13 by life, heat storage water tank 15 is communicated with by the hot water tap 16 of heat-exchanger pump 17 with the user place, described condenser 4 is connected with open-type cooling tower 11 with cooling water pump 12 by medium circulation pipeline 22, chilled water pipeline 21 is linked to be the loop through air-conditioning water pump 10 and room conditioning end-equipment sky, a sealed cooling tower 8 that is used to put enfleurage heat in parallel on chilled water pipeline 21 with the room conditioning end-equipment, sealed cooling tower 8 is positioned at outdoor, on chilled water pipeline 21, be connected with magnetic valve 9, air intake place at the room conditioning end-equipment is provided with air temperature sensor 5, the life that is back to heat recovering heat exchanger 2 at heat storage water tank 15 is with being connected with hot water temperature's sensor 14 on the hot-water line 20, air temperature sensor 5 is connected with the signal input part of hot water temperature's sensor 14 with PLC switch board 18, the signal output part of PLC switch board 18 and magnetic valve 9 control connections.Described room conditioning end-equipment is air-conditioning box 6 and fan coil 7.
Sealed cooling tower in the utility model is the thermal balance equipment in the water cooled refrigeration heat recovery machine group system.Because the effect of sealed cooling tower is to make air conditioning water and air carry out heat exchange, because air conditioning water is to operate in the air conditioner end equipment, in the water impurity can not be arranged, otherwise therefore easy blocking pipe, select sealed cooling tower to put enfleurage heat for use.
Operation principle of the present utility model is:
The temperature of cold air-conditioning reaches when setting value when summer; just indoor when not needing cold; usually compressor requires and can shut down according to control; but at this moment life does not reach 55-60 ℃ of setting value with hot water in the heat storage water tank; requiring also needs to open compressor according to hot water heats; at this moment indoor the absorption less than heat just need be to outdoor, absorption from atmosphere.According to the magnetic valve on the pipeline of the outdoor sealed cooling tower of the instruction unpack of PLC switch board, air conditioning water flows into sealed cooling tower and outside atmosphere is carried out the heat exchange heat absorption, the electric heater height that the thermal efficiency ratio of this device is pure, because the efficiency ratio of refrigeration machine refrigeration in summer is generally COP=3-4, and the heat that the electric power of one kilowatt of the thermal efficiency consumption of electric heater obtains is 860kCal/kW, then by refrigeration machine be exactly it 3-4 doubly.
So just can make water cooled refrigeration machine recuperation of heat unit in summer, or even spring and autumn can both continuous operation, satisfy the requirement of two operating modes, be the requirement of satisfying indoor cold operating mode on the one hand, in 1 year three season, utilized the life of heating of the used heat of open cold operating mode to reach 55-60 ℃ requirement on the other hand with hot water.The used heat of 30% when common buildings only need be with cold air-conditioning oepration at full load just can satisfy the requirement of life with the hot water thermal supply.
