A kind of high-efficiency air cooling, the dual-purpose condenser of water-cooled
The utility model technology relates to a kind of high-efficiency air cooling, the dual-purpose condenser of water-cooled, belongs to heat transmission equipment technical fields such as refrigeration air-conditioner.
In the refrigeration plant design, condenser is one of indispensable capital equipment.Refrigeration plant adopts water-cooled condenser compared with adopting the air-cooled condenser unit operation more steadily with efficient.Yet, under some occasion or purposes, wish again to reclaim and to utilize condensation heat.Such as freezing, the refrigerated display cabinet that are arranged in the large supermarket.When summer operation, the condensation heat that unit produces all is disadvantageous to indoor environment and unit operation, and adopting air cooled condenser is not a good strategy, if at this moment adopt water cooled condenser will migrate out condensation heat outdoor very easily; When equipment moved in the winter time, the condensation heat that unit produces was favourable to indoor environment, can increase indoor heating load, lowered the heating of house expense, was relatively to help saving the heating energy if at this moment adopt air cooled condenser.
Summary of the invention
Condenser heat discharging for convenience and the mutual conversion of recycling, the utility model technology provides a kind of high-efficiency air cooling, the dual-purpose condenser of water-cooled.This condenser has also increased the cooling system heat exchange coil except the heat exchange coil with cold-producing medium.Utilize band-tube type heat exchanger, on the condenser fin pipe, increased the heat exchange coil unit of water-cooled circulation, realized the air-cooled and water-cooled integrated of condenser.
A kind of high-efficiency air cooling, the dual-purpose condenser of water-cooled mainly are made of jointly condenser fan, condenser frame, condensation heat transfer coil pipe, cooling water heat exchange coil, condenser heat exchange fin.The spacing of interting on heat exchange coil is the aluminum heat exchange fin of 1.5mm-6mm, fin height be condense the coil pipe caliber 1.2-4 doubly, condensation heat transfer coil pipe and cooling water heat exchange coil arranged crosswise are with convenient processing with weld; Condenser fan is fixed on the condenser frame, with the heat-transfer surface vertical diameter to installation.
Useful result of the present utility model is, when summer or refrigeration unit condensation load were higher, the logical cooling water heat exchange coil heat exchange of the condensation heat that unit produces was transferred to outdoor; During winter operation, be used for indoor heating, reduce the energy resource consumption of indoor heating in winter by opening the recyclable condensation heat of condenser fan.
Description of drawings
Below in conjunction with drawings and Examples the utility model technology is further specified.
Figure one is the novel structural representation of this use
Among the figure: 1 condenser fan; 2 cooling water coil water inlets; 3 cooling water coil delivery ports; 4 condensation of refrigerant coil pipes inlet; The outlet of 5 condensation of refrigerant coil pipes; 6 condenser frames; 7 condenser heat exchange fins; A condensation heat transfer coil pipe; B cooling water heat exchange coil;
The specific embodiment
Embodiment as shown in Figure 1, when summer, flow through in the condensation heat transfer coil pipe (A) of the gaseous refrigerant of HTHP in condenser, by interting after cooling water heat exchange coil (B) heat exchange on the condenser heat exchange fin (7), at the liquid refrigerant of condensation of refrigerant coil pipe outlet (5) formation high pressure low temperature, keep the normal operation of refrigeration unit.At this moment, condensation fan (1) is not opened, and promptly the unit condenser is a water cooled condenser.In the time of in the winter time, cooling water is emitted (in case outdoor heat exchange pipeline time bursting by freezing) in the winter time in the cooling water coil, and condenser fan (1) heat exchange of condensation of refrigerant heat exchange by opening is so that keep the normal operation and the indoor condensation of refrigerant heat of rationally utilizing of unit.
