Description
(1) technical field
The present invention relates to the use of cascade heat pump circulation refrigerating capacity three-level recycling public building, bath center, drying plant,
Air draft/idle air cooling sensible heat, condensation latent heat, frosting latent heat in various mines, and added using its heating capacity parallel connection switching, step
The multiduty a kind of big temperature rise of antifreezing agent multipaths such as hot fresh air, return air, hot water takes hot air draft source vapor cascade heat pump.
(2) background technique
(1) building consumes global half electric energy, air-conditioning and heating consumption building half electric energy, the U.S., Japan air-conditioning with
Heating consumes the 1/3 of its total electric energy, and Sweden even consumes the 45% of its total electric energy；
(2) extremely toxic substance and germ are generated, and distributes radioactive building, can not be utilized due to there is serious pollution
Return air is had to using single flow air-conditioning, therefore loses huge heat with huge exhaust air rate；
(3) in the air return type air-conditioning of the public buildings such as computer room, arenas, hospital, supermarket, since fresh air volume is huge；It arranges simultaneously
Wind epidemic disaster is Fresh air handing and mixed target value closest to indoor design operating condition, therefore is contained in air draft a large amount of available
Heat；
(4) since exhaust air rate is smaller in common air return type air-conditioning, fresh air is caused to recycle air draft thermal Finite, therefore can return
Complete hot regenerator is arranged between wind process chamber back segment and fresh air duct, heats 12-14 DEG C of dew using the summer full heat of 37-40 DEG C of fresh air
Point return air, had not only reduced reheating power consumption but also cooling treatment fresh air；
(5) fresh air sucks surrounding air, and air draft breathes out room air, forms the breathing of building, remains indoor by changing wind
Air quality；Existing Fresh air handling units summer passes through electric refrigerated dehumidification, cooling fresh air, and winter is new by the heating of the water capacities such as electric heating pump
Wind；Its new wind load accounts for air conditioner load up to 20-30%, therefore is to meet new wind load using fresh air recycling air draft heat
The effective energy conservation measure of air-conditioning system.The Fresh air handing power consumption of 70-80% is saved, the operation of air conditioner electricity charge for saving 10-20% are converted into,
It is the important channel for reducing air-conditioning power consumption.
And the existing various technologies that fresh air recycling air draft heat is realized using heat pump, main problem is:

Sensible heat, condensation latent heat, frosting latent heat.
(2) condenser of ordinary single-stage heat pump cycle can only provide big flow small temperature difference water circulation, new therefore, it is difficult to realize
Efficient, the inexpensive optimization design of fresh air coil pipe in blower fan group, it is difficult to realize the big temperature rise of its winter, etc. water capacities heating fresh air.
(3) reheat coils of ordinary single-stage heat pump cycle and fresh air coil design, the formed small temperature lifting/lowering of big flow change
Heat not only increases the throwing of air draft backheat case, Fresh air handling units, water circulating pump, antifreezing agent pump, circulating line and its various control valves
Money, and increase the operation power consumption of water circulating pump and antifreezing agent pump.
(4) ordinary single-stage heat pump cycle is difficult to realize the defrosting of winter reheat coils.
(5) ordinary single-stage heat pump cycle is difficult to that the opposite water capacity of fresh air is greatly reduced, to be difficult to realize fill indoors
Divide and absorb vapor, to provide free steam calorific potential for air draft backheat.
(6) ordinary single-stage heat pump cycle does not account for, and how to efficiently use solar energy.
