The beneficial effect of a kind of unitary air handling unit with dehumidifier reheat machine of the utility model is:
This kind of unitary air handling unit with dehumidifier reheat machine, compact conformation, saves space, design science, easy for installation; The defect of the energy dissipation of the cold-hot counteraction that the reheating overcoming existing air-conditioning system primary retirn air and air mixing existence causes, comprehensive utilization cool-down dehumidification, condensation reheating power-saving technology, the energy consumption of effective solution air dewetting air-conditioning system own is high, condensation waste heat reclaims difficult problem, the cold and hot phenomenon that offsets that can effectively avoid exist summer, reaches the object that total system is energy-conservation; There is good actual application value and promotional value.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this kind of unitary air handling unit with dehumidifier reheat machine is described further:
Fig. 1 is the structural representation of this kind of unitary air handling unit with dehumidifier reheat machine.
In figure: 1 be air inlet, 2 be fan section, 3 be filter, 4 be Surface cooling coil, 5 be dehumidifier reheat machine, 5.1 be dehumidifier coil pipe, 5.2 be compressor, 5.3 be hot coil again, 5.4 be throttling arrangement, 6 be air outlet.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the utility model is further described.
As shown in Figure 1, this a kind of unitary air handling unit with dehumidifier reheat machine, comprise the air-treatment function section of air inlet 1, fan section 2, filter 3, Surface cooling coil 4, dehumidifier reheat machine 5 and air outlet 6 formation arranged in turn, Surface cooling coil 4 pairs of air are adopted to carry out reducing temperature and humidity pretreatment, thus reduce the consumption of low-grade low-temperature receiver, reduce energy consumption, reach energy-saving effect;
Described dehumidifier reheat machine is refrigerant direct-evaporation-type cooling cycle system, it comprises dehumidifier coil pipe 5.1, compressor 5.2, reheating coil pipe 5.3 and throttling arrangement 5.4, the high voltage interface of described compressor 5.2 connects reheating coil pipe 5.3, throttling arrangement 5.4, dehumidifier coil pipe 5.1 successively, the other end of described dehumidifier coil pipe 5.1 is connected with the low-pressure end of described compressor 5.2, form refrigerating circuit, dehumidifier coil pipe 5.1 is utilized to carry out secondary dehumidifying to pretreated air, and utilize condensation waste heat to add hot-air, heat is again provided, there is significant energy-saving effect.
Concrete, described Surface cooling coil 4 is direct-expansion coil, is arranged on the inlet side of filter 3, and the first order is lowered the temperature, effect on moisture extraction is better.
Concrete, described dehumidifier coil pipe 5.1 is arranged on the air side of described Surface cooling coil 4, and described reheating coil pipe 5.3 is arranged on the air side of described dehumidifier coil pipe 5.1; Dehumidifier coil pipe 5.1 pairs of air carry out degree of depth dehumidifying, and reheating coil pipe 5.3 pairs of air carry out reheating, both reach effect on moisture extraction, and again condensation heat are used for reheating, economize energy.
