Then PLC control programs of an air conditioning unit are reasonably programmed, conditions are fed back according to temperature and humidity signals collected from a workshop to control the open degree of the general motorized valve located on the water inlet pipe and the open degree of the auxiliary motorized valve located on the vice coil pipe in real time, flow of chilled water entering the main coil pipe and the auxiliary coil pipe of the surface air cooler is controlled, the phenomenon of temperature raising due to air supplying and heating on the unit through a steam heat exchanger is reduced, and the purposes of energy conservation and steam energy consumption reduction are achieved.
Description
Technical field
The utility model belongs to the energy-conserving and environment-protective technical field, relates in particular to a kind of combined air-conditioner.
Background technology
In modern industry enterprise, combined air conditioning box has obtained extensive application in industrial premises, people are when enjoying its huge ambient temperature and humidity control ability and control accuracy to the full, more and more pay close attention to the huge energy resource consumption that it brings, energy resource consumption while how to reduce the combined air conditioning box operation, become one of major issue of manufacturer and applying unit concern.
generally, combined air conditioning box mainly contains pressure fan, surface cooler, vapor heat exchanger, the parts such as humidifier and air cleaner form, aspect energy-conservation, people are often with the converting operation of pressure fan, selecting of high efficiency humidifier and vapor heat exchanger, and scientific and reasonable operating unit etc. is as main conservation measures, ignore the energy-conservation research to surface cooler, regard surface cooler as simple copper pipe and wear copper fin, copper pipe is worn aluminium fin or aluminum pipe and is worn the heat exchanger coil that aluminium fin etc. forms, only from how improving the coefficient of heat transfer, set about improving the heat transfer effect of surface cooler, but As time goes on, the surface cooler material occurs aging, fouling or the dirty phenomenon such as stifled, have a strong impact on its heat exchanger effectiveness, energy-saving effect worse and worse, the energy saving technical reconstruction of surface cooler is in the stagnation state always, energy-saving effect is further developed.
From above-mentioned analysis as can be known, the surface cooler of combined air conditioning box is mainly worn aluminium fin etc. by copper pipe and is formed heat exchanger coil, and electric control valve is installed on its chilled water main water inlet tube, is used for regulating the flow by chilled water in surface cooler.Between surface cooler and pressure fan, vapor heat exchanger is installed, is used for improving the temperature of environment in workshop.In summer, during higher than technological standards, the electric control valve that is positioned on the surface cooler main water inlet tube is opened automatically when temperature in workshop, reduces the temperature in workshop; In winter, during lower than technological standards, the electric control valve that is positioned on the vapor heat exchanger main steam inlet tube is opened automatically when temperature in workshop, improves the temperature in workshop, thereby meets technological requirement.but during summer, often occur in workshop that air themperature is low, the opposition operating mode phenomenon that relative humidity is large, the humiture index can not meet technological requirement, at this moment, the electric control valve that is positioned on the vapor heat exchanger main steam inlet tube can be opened automatically, allow steam enter in vapor heat exchanger, wind pushing temperature to unit suitably raises, figure wet according to enthalpy of humid air as can be known, when the absolute moisture content of humid air is constant, when the humid air temperature raises, relative humidity descends, until ambient temperature and humidity meets technological requirement, so just occurred " being sent to the air in workshop after cooling is processed, heat temperature raising again " phenomenon, cause the huge waste of " cold " and " steam " energy.
The utility model content
The utility model, in order to solve weak point of the prior art, provides the combined air-conditioner of a kind of energy savings, good effect of heat exchange.
for solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of combined air-conditioner, comprise the casing with air inlet, be located at surface cooler and air exhauster in casing, the air outlet of air exhauster stretches out outside casing, described surface cooler comprises the master pipe, bracket panel pipe and fin, the water inlet end of master pipe and bracket panel pipe is connected with a water inlet pipe jointly, master pipe and bracket panel pipe are connected with an outlet pipe jointly, water inlet pipe and outlet pipe all stretch out outside casing, water inlet pipe is provided with and is positioned at the outer total electric control valve of casing, the bracket panel pipe is provided with the secondary electric control valve that is positioned at bracket panel water inlet tube end.
Described surface cooler is between casing air inlet and air exhauster.
adopt technique scheme, the utility model is under the prerequisite of the normal operation that guarantees unit, principle in line with " reducing vapor heat exchanger reheats unit blasting air ", the surface cooler internal structure is improved, when adopting copper pipe to wear aluminium fin etc. to form heat exchanger coil, the surface cooler internal structure is carried out the reasonably optimizing design, surface cooler is designed to the heat exchanger that is formed by master pipe and bracket panel pipe, again the PLC control program of air-conditioning unit is rationally programmed, according to the temperature-humidity signal feedback that gathers in workshop, control total electric control valve of being positioned on water inlet pipe and the secondary motorized adjustment valve opening on the bracket panel pipe in good time, control the flow that chilled water enters master pipe and bracket panel pipe in surface cooler, reduce the phenomenon of vapor heat exchanger to the unit blasting air heat temperature raising, reach the purpose of energy-saving steam energy consumption.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
as shown in Figure 1, a kind of combined air-conditioner of the present utility model, comprise the casing 2 with air inlet 1, be located at surface cooler and air exhauster 3 in casing 2, the air outlet of air exhauster 3 stretches out outside casing 2, described surface cooler comprises master pipe 4, bracket panel pipe 5 and fin 6, the water inlet end of master pipe 4 and bracket panel pipe 5 is connected with a water inlet pipe 7 jointly, master pipe 4 and bracket panel pipe 5 are connected with an outlet pipe 8 jointly, water inlet pipe 7 and outlet pipe 8 all stretch out outside casing 2, water inlet pipe 7 is provided with and is positioned at the outer total electric control valve 9 of casing 2, bracket panel pipe 5 is provided with the secondary electric control valve 10 that is positioned at bracket panel pipe 5 water inlet ends.Surface cooler is between casing 2 air inlets and air exhauster 3.
When the utility model used in work, total electric control valve 9 and secondary electric control valve 10 all were in full-gear, and the chilled-water flow that enters in surface cooler is regulated by total electric control valve 9, thereby guaranteed that the ambient temperature and humidity in workshop meets technological requirement.While occurring air themperature is low, relative humidity is large opposition operating mode in workshop when summer, reduce or close the aperture of secondary electric control valve 10, make the part return air of unit not cooled cooling by this part wind of bracket panel pipe 5(, be equivalent to secondary return air), sent by air exhauster 3 again, what greatly reduce like this vapor heat exchanger adds heat again, thereby reduce, until stop steam, enters the phenomenon that vapor heat exchanger heats, and reaches the purpose of saving the steam energy consumption.
