The heat pump set comprises a refrigerant recycling system, a fresh air pipeline, and an exhaust air pipeline, wherein the refrigerant recycling system comprises a compressor, an air cooling/heating device, a bidirectional expansion valve and an air heating/cooling device which are connected in order, two ends of the compressor are connected with the air cooling/heating device and the air heating/cooling device via a four-way reversing valve, a bypass pipeline and a bypass adjusting valve are connected between the fresh air pipeline and the exhaust air pipeline, a draught distributing box is arranged in the connecting position of the bypass pipeline and the fresh air pipeline, and a draught mixing box is arranged in the connecting position of the bypass pipeline and the exhaust air pipeline. In summer, fresh air passes through the draught distributing box, and via the bypass pipeline part of the fresh air enters the draught mixing box to mix with exhaust air, thereby increasing the air quantity of an air heating device, reducing the condensation temperature of the refrigerant, solving the problem that the condensation temperature is too high so that the coldness amount in the exhaust air can not be completely recycled, and improving the working efficiency of the set.
Description
Technical field
The utility model relates to a kind of wet source pump that reclaims of new wind air draft heat with the bypass adjusting, belongs to field of air conditioning.
Background technology
In the building central air-conditioning system, the energy consumption of handling new wind roughly accounts for 30%～35% of total energy consumption, and the novel wind energy consumption of luxurious hotel or office building is generally up to 50%, and particularly the new wind load of marine air conditioning possibly surpass 60%.Because resh air requirement is big, and the difference of temperature, humidity and the indoor exhaust wind of new wind is big, if air draft is not carried out the recovery of heat and humidity, the energy consumption of then handling new wind is huge, causes the severe energy waste phenomenon.
Conventional heat pump heat is wet to be reclaimed new air draft blower fan group and receives the air draft quantitative limitation, and during cooling condition, the cold that reclaims in the air draft can cause that condensation temperature is too high, can't reclaim cold discarded in the air draft fully, causes the inefficiency of unit, energy consumption big.
Summary of the invention
In order to solve above defective; The utility model proposes a kind of wet source pump that reclaims of new wind air draft heat with the bypass adjusting; Improve the operating efficiency of source pump, solved conventional source pump summer because of the too high problem that can't reclaim cold in the air draft fully of condensation of refrigerant temperature.
A kind of wet source pump that reclaims of new wind air draft heat with the bypass adjusting; Form by refrigerant-cycle systems, fresh air pipeline and air draft pipeline; Wherein, Refrigerant-cycle systems comprises successively compressor, air cooling device, two-way expansion valve and the air heat/cooler that connects, and is connected with four-way change-over valve between the two ends of compressor and air cooling device and the air heat/cooler; Fresh air pipeline passes through from air heat/cooler, and the port of export of fresh air pipeline is equipped with new wind blower fan; The air draft pipeline passes through from air cooling device, and the port of export of air draft pipeline is equipped with the air draft blower fan; Also be provided with a wet recover of runner heat, said fresh air pipeline and air draft pipeline pass through from the wet recover of runner heat; Be connected with bypass line and bypass regulator valve between fresh air pipeline and the air draft pipeline.
The junction of said bypass line and fresh air pipeline is provided with draught distributing box, and the junction of bypass line and air draft pipeline is provided with mixed bellows.
Said fresh air pipeline and air draft pipeline be reverse passing through from the wet recover of runner heat respectively.
This source pump makes the air (new wind) of outdoor entering and the air (air draft) of indoor discharge carry out heat, wet exchange through the wet recover of runner heat; Open bypass regulator valve as required; The new wind of part is branched in the air draft pipeline,, increase the air quantity of the air cooling device of flowing through to remedy the deficiency of air draft air quantity; Solved and reclaimed when freezing summer that refrigeration duty receives the exhaust air rate restriction in the air draft, cause the too high problem that can't reclaim cold discarded in the air draft fully of heat pump condensation temperature; Thereby reduce the condensation temperature of cold-producing medium in summer, fully reclaim the cold in the air draft, improve the operating efficiency of unit.
