Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.

The specific embodiment of a kind of energy-saving unitary air handling unit of the present utility model as shown in Figure 1, comprise cabinet 1, described cabinet 1 is built-in with master meter cooling coil 2, blower fan 7 and pre-cooling of fresh air coil pipe 3, master meter cooling coil 2 is located between pre-cooling of fresh air coil pipe 3 and blower fan 7, the fresh wind port 11 that pre-cooling of fresh air coil pipe 3 is right against cabinet 1 is arranged, the below of master meter cooling coil 2 is provided with the drip tray 4 for collecting condensed water, be provided with the pipeline 5 for carrying condensed water between drip tray 4 and described pre-cooling of fresh air coil pipe 3, pipeline 5 is provided with water pump 6.

By connecting the water pump 6 on the pipeline 5 of drip tray 4 and pre-cooling of fresh air coil pipe 3 and pipeline 5, condensed water in drip tray 4 is delivered to pre-cooling of fresh air coil pipe 3, at blower fan 7 under effect, outside new wind enters pre-cooling of fresh air coil pipe 3 through fresh wind port 11, in the new wind of high temperature and pre-cooling of fresh air coil pipe 3, the condensed water of lower temperature carries out heat exchange, achieve new wind cooling preprocessing function, and then reduce the temperature of new wind, new wind after cooling enters master meter cooling coil 2 again, this greatly reduces the thermic load of air-conditioner set, and then reduce the overall energy consumption of air-conditioner set, reach the object of energy-saving and emission-reduction.

Concrete, for reaching better cooling-down effect to new wind, the air intake surface of pre-cooling of fresh air coil pipe 3 is just arranged fresh wind port 11, and the whole new wind that fresh wind port 11 is come in is all first through the cooling pretreatment of pre-cooling of fresh air coil pipe 3; For making the new wind after cooling enter master meter cooling coil 2 smoothly, the outlet air surface of pre-cooling of fresh air coil pipe 3 is just arranged the air intake surface of master meter cooling coil 2; After new wind after lowering the temperature and master meter cooling coil 2 carry out heat exchange, for making high temperature gas flow discharge cabinet 1 fast, the outlet air surface of master meter cooling coil 2 is just arranged the air inlet of blower fan 7, and air is discharged cabinet 1 by the air outlet of blower fan 7.

Concrete, because water pump 6 is that the cool solidifying water in drip tray 4 is delivered to pre-cooling of fresh air coil pipe 3, for reaching better defeated effect, water pump 6 is arranged near drip tray 4 place.

In the present embodiment, for reaching effect of better catchmenting, also in order to reduce the conveying difficulty of condensed water, drip tray 4 is set to the drip tray 4 with staggered floor construction, concrete, drip tray 4 is provided with two-layer up and down, be respectively ground floor water leg 41 and with second layer water leg 42, ground floor water leg 41 is communicated with second layer water leg 42 and second layer water leg 42 is positioned at the below of ground floor water leg 41.

The groove depth of ground floor water leg 41 is less than the groove depth of second layer water leg 42, be convenient to condensed water and be all pooled to second layer water leg 42, and one end that pipeline 5 connects drip tray 4 is inserted in second layer water leg 42, the conveying difficulty of condensed water can be effectively reduced like this.

Concrete, ground floor water leg 41 is positioned at immediately below master meter cooling coil 2, and the bottom land area of ground floor water leg 41 is greater than the bottom land area of second layer water leg 42, ground floor water leg 41 mainly plays the function of collecting condensed water, and second layer water leg 42 mainly plays the function collecting and store condensed water, thus the bottom land area of second layer water leg 42 is less, makes condensed water have certain degree of depth, be convenient to the conveying of condensed water like this to reach rapid aggregation condensed water.

In the present embodiment, fresh wind port 11 is provided with the new air-valve for controlling new wind air force, and for suitably regulating the temperature and humidity of new wind, cabinet 1 offers return air inlet 12 near fresh wind port 11 place, same, return air inlet 12 is provided with the air returning valve for controlling return air air force.When the new wind in outdoor exceedes certain high temperature, new wind and return air mixing can reach the temperature reducing overall new wind, also can reduce the thermic load of air-conditioner set, and then reach energy-conservation object.

Above embodiment is only in order to illustrate the technical solution of the utility model, but not the restriction to the utility model protection domain, can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
