Though 2, there is not cross pollution in sheet fin type heat recovery unit, can only reclaim sensible heat, and is powerless aspect the latent heat recovery;
3, heat recovery efficiency is limited, also can't reach the operating point of indoor requirement by the handled new wind of existing recuperation of heat unit, also configuration cooling device or heater in addition;
4, above-mentioned two kinds of recuperation of heat modes all exist heat exchanger to cross defectives such as wind resistance is big;
5, after above-mentioned two kinds of recuperation of heat mode energy reclaimed, its output can all be lower than the energy position that is recovered air in the position;
6, the heat exchanger effectiveness of traditional structure is subjected to the influence of new wind, the air draft temperature difference and relative humidity difference, and promptly when new wind and temperature of outgoing air and relative humidity homogeneous phase while, the heat recovery efficiency of this moment also is zero.
Summary of the invention
The purpose of this utility model is to provide a kind of air heat-recovery heat pump unit, and the utility model can be effectively carries out recuperation of heat to the energy of air draft and part outside air, and the recuperation of heat amount is big, recuperation of heat efficiency height; Can increase substantially simultaneously the energy position of output, can full operating mode carry out recuperation of heat, it is less that heat recovery efficiency is influenced by new wind and air draft energy difference, and do not have cross pollution between new wind and air draft.
The utility model is achieved through the following technical solutions:
A kind of air heat-recovery heat pump unit comprises fresh flue, exhausting duct; Also include compressor, first heat exchanger, second heat exchanger and restricting element, first heat exchanger, second heat exchanger and restricting element are by tube connector connection formation heat exchanging pipe, the two ends of this heat exchanging pipe communicate with the two ends of compressor, first heat exchanger, second heat exchanger place respectively in fresh flue and the exhausting duct, are equipped with blower fan in fresh flue and exhausting duct.
Further structure of the present utility model is:
Also be provided with filter in described exhausting duct, fresh flue, filter can filter the air in exhausting duct and the fresh flue.
This heat-recovery heat pump also comprises cross valve, and the two ends of described heat exchanging pipe, the high-pressure side of described compressor, low-pressure end communicate with four ports of cross valve; Can change the flow direction of heat-exchange working medium by cross valve, so that the utility model is applicable to summer or winter respectively, particularly, the utility model has following two kinds of operating modes:
1, in summer, in the fresh flue temperature of air higher and in the exhausting duct temperature of air lower, when compressor operating, first heat exchanger uses as evaporimeter and the airborne heat in absorption fresh flue, second heat exchanger uses as condenser, and utilizes the cold wind in the exhausting duct that condenser is cooled off;
2, in the winter time, the temperature of air is lower and air themperature in the exhausting duct is higher in the fresh flue, when compressor operating, first heat exchanger uses as condenser, and utilizing that cold wind cools off condenser in the fresh flue, second heat exchanger uses as evaporimeter and absorbs the airborne heat of exhausting duct;
The utility model is under the effect of compressor, heat-exchange working medium is realized heat exchange between first heat exchanger, second heat exchanger, and between fresh flue and exhausting duct, form heat pump, in summer, source pump is with the airborne heat absorption in fresh flue and be released in the cold air of exhausting duct, and the temperature of air in the fresh flue is reduced; In winter, source pump is with the airborne heat absorption of exhausting duct and the air themperature in the fresh flue is raise.Realize the recycling of heat energy, improved efficiency; In heat recycle process, there is not cross pollution between fresh flue and the exhausting duct, the air quality height, and the new wind after handling by source pump can directly enter into indoor room, do not need to add special cooling device or heater again, and deployment cost is low.
Be provided with fresh wind port away from its air outlet one end on described exhausting duct, be provided with valve at this fresh wind port place, when valve open, this fresh wind port can connect extraneous space and described exhausting duct.When valve open, can in exhausting duct, carry new wind by fresh wind port, can change the temperature of air in the exhausting duct, and then improve the recuperation of heat effect of heat pump.
