Description
Technical field
The present invention relates to a kind of air-source flexibility water chiller-heater unit and operation method, belong to heat supply and field of air conditioning.
Background technology
Air source cold-hot water dispenser group is a kind of highly effective refrigeration heating equipment, takes heat from outdoor air in the winter time and to interior
Heat supply, in summer to outdoor air heat release and to indoor cooling, to meet the air-conditioning of building and hot water demand.It is cold according to outside
But the difference of mode, air source cold-hot water dispenser group are broadly divided into direct air-cooled and water-cooled again.
Directly air-cooled cold and hot water supply system has the advantages that easy for installation, the scope of application is broad, floor space is small.It is such
System is radiated in summer using air cooling heat exchanger to surrounding air, and outdoor air obtains sensible heat and heated up.With water cooled system phase
Than the condensation temperature of direct air-cooled system is generally higher, and then reduces the performance of water chiller-heater unit cooling condition.
Directly air-cooled cold and hot water supply system takes heat from outdoor air in the winter time, asking for frosting in practical application be present
Topic, particularly relatively low in temperature and area that humidity is very big, the frost of outdoor air cooling heat exchanger are especially serious.Existing defrosting
Scheme has refrigerant inverse defrosting, thermal storage defrosting and waste heat to defrost three kinds.First two scheme during defrosting can completely or
Person's some effects user side heating effect, although waste heat defrosting does not interfere with indoor heating effect, the one of unit can make it that
Secondary energy efficiency declines and does not reach the purpose of energy-conserving and environment-protective.
Under water cooled system cooling in summer operating mode, the release end of heat of water chiller-heater unit leads to cooling water heat release, then by cooling water
Enter cooling tower, make its heat release into surrounding air.Because the cooling water temperature that water cooled system is produced is usually less than air-cooled heat exchange
The condensation temperature of device, therefore water cooled system performance is air-cooled better than direct under cooling in summer operating mode.
And in the winter time under heating condition, common cooling tower can not extract heat from surrounding air, without suitable low product
Position thermal source is to ensure multiple air conditioner heat pump system normal operation.Chinese patent (Authorization Notice No. CN203934451U) proposes
The method that hot systems are taken by the use of solution spraying air structure energy tower as heat pump multi-connected machine, though solving, cooling water is antifreeze to ask
Topic, but still exist and take heat inadequate, the problems such as solution cost is high, regeneration energy consumption is high.
Therefore, research and development have the characteristics that refrigerated efficient, heat supply continuous-stable, reliable air source cold-hot water dispenser group are
The further important channel of development and lifting air source cold-hot water unit performance.
