The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the defective of the energy dissipation of the hot cold-hot counteraction that causes again that has air-conditioning system primary retirn air and new wind mixing existence now, to the recovery of condensation waste heat energy, provide a kind of two low-temperature receiver degree of depth dehumidifying fresh air conditioner systems with the condensation heat recovery.
For achieving the above object, the utility model consists of new wind processing capacity section by the surface cooler that sets gradually, straight swollen dehumidification system, condensation waste heat retracting device.
Concrete: described surface cooler comprises the chilled water coil pipe that is arranged on into new wind side.Described straight swollen dehumidification system is the direct-evaporation-type refrigerating plant, and it comprises compressor, condenser, device for drying and filtering, expansion valve, evaporimeter; The high voltage interface of described compressor connects condenser, device for drying and filtering, expansion valve, evaporimeter successively, and the other end of evaporimeter is connected with the low-pressure end of compressor, consists of thus a refrigerating circuit; Further, described evaporimeter is arranged on the air side of described surface cooler, and described condenser is arranged on the air side of described evaporimeter.Described surface cooler can also be chilled water coil.Described straight swollen dehumidification system can also be condensation heat extraction temperature adjusting and dehumidifying system.Described straight swollen dehumidification system is the refrigerating circuit that single compressor consists of.Described straight swollen dehumidification system can also be the refrigerating circuit that is made of two compressors.This air-conditioning system comprises new air-valve, fan assembly, filter, air outlet, and described new air-valve, fan assembly, filter bits are in the front side of described new wind processing capacity section, and described air outlet is positioned at the rear side of described new wind processing capacity section.
The beneficial effects of the utility model are:
(1) adopt the pyrometric scale cooler to carry out precooling treatment to new wind, thereby reduce the consumption of low-grade low-temperature receiver, reduce energy consumption, reach energy-saving effect;
(2) adopt straight swollen dehumidification system to carry out degree of depth dehumidifying to pretreated new wind, and utilize condenser used heat to add hot-air, have significant energy-saving effect.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Number in the figure explanation: the new air-valve of 1-, 2-fan assembly, 3-filter, 4-chilled water coil pipe, 5-evaporimeter, 6-condenser, 7-compressor, 8-air outlet, 9-device for drying and filtering, 10-expansion valve.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described further.
Two low-temperature receiver degree of depth dehumidifying fresh air conditioner systems with the condensation heat recovery of the present utility model, as shown in Figure 1, it consists of new wind processing capacity section by the surface cooler that sets gradually, straight swollen dehumidification system, condensation waste heat retracting device.
Concrete, surface cooler comprises that the chilled water coil pipe 4(surface cooler that is arranged on into new wind side can also be chilled water coil), be arranged on the air side of the filter 3 of hereinafter addressing.Straight swollen dehumidification system is the direct-evaporation-type refrigerating plant, and it comprises compressor 7, condenser 6, device for drying and filtering 9, expansion valve 10, evaporimeter 5; The high voltage interface of compressor connects condenser 6, device for drying and filtering 9, expansion valve 10, evaporimeter 5 successively, and the other end of evaporimeter 5 is connected with the low-pressure end of compressor, consists of thus a refrigerating circuit; Further, evaporimeter 5 is arranged on the air side of surface cooler, and condenser 6 is arranged on the air side of evaporimeter 5.Straight swollen dehumidification system can also be condensation heat extraction temperature adjusting and dehumidifying system.Straight swollen dehumidification system is the refrigerating circuit that single compressor consists of, perhaps the refrigerating circuit for being made of two compressors.This air-conditioning system comprises new air-valve 1, fan assembly 2, filter 3, air outlet 8, new air-valve 1, fan assembly 2, filter 3 are positioned at the front side of new wind processing capacity section, it is (concrete that air outlet 8 is positioned at the rear side of new wind processing capacity section, fan assembly is in new wind introduction place of 2 new air-valves 1, filter 3 is in the air side of fan assembly 2, and air outlet 8 is in the air side of condenser 6).
