Description
Technical field
Present invention relates in general to air-conditioning technical fields, and utilize air conditioning terminal condensed water more particularly, to a kind of
To improve the system and air cooled heat pump of air cooled heat pump refrigeration performance.
Background technique
With the development of society and the continuous improvement of living standards of the people, air-conditioning has come into huge numbers of families.Currently, family
It all can be described as air-cooled sky with the air-cooled heat pump type air conditioner that separate type air conditioner, Centralized Air-conditioning in Public Buildings (VRV) and the quotient people use with
Adjust unit.Air cooled heat pump generally aspirates air by axial flow blower, so that air is flowed and carries out forced heat-exchanging with fin,
Achieve the purpose that cooling fins, unit is maintained to freeze.When unit is run, air is horizontal to plunder fin, and refrigerant is transmitted to wing
The heat on piece surface is taken away, and the temperature of air also increases.When the temperature of air and the temperature close of fin surface or maintain an equal level
When, the heat on fin can not shed, and high temperature protection occurs in unit, and then compressor stops refrigeration.In addition, due to the ratio of air
Heat (being 1.0kj/ (kg DEG C) under mark condition) is smaller, and in the case where flow is certain, the heat that the unit time is taken away is also smaller, causes
Efficiency (EER) differs larger with water chiller, water chiller generally in 3.0 or so (under mark conditions) when air cooled heat pump freezes
Refrigeration efficiency EER is about 5.5 (under mark conditions).
Summer temperature is high, and air humidity is big, and horizontal plunder after air conditioning terminal surface air cooler is cooled of room air sends interior back to, so
Iterative cycles reduce room temperature.Since the temperature of surface air cooler is lower than the dew-point temperature of room air, air circulation is cold indoors
But a large amount of condensed waters can be precipitated during, condensed water water temperature is generally at 20 DEG C or so.In most situations, condensed water passes through sky
It adjusts the water-collecting tray below the surface air cooler of end to flow to condensate pipe, is then immediately discharged in sewer, is not only water resource in this way
Waste, the even more waste and loss of cold source of air conditioning.
The operating temperature of water chiller cooling tower standard condition is generally 38 DEG C/33 DEG C, and work water temperature significantly larger than condenses
Water water temperature.When air-cooled unit freezes, the unsmooth or outdoor temperature of unit ambient air circulation is higher, can all lead to unit surrounding air
Temperature increases.Under bad working environments, unit ambient air temperature seriously threatens the normal operation of unit up to 45 DEG C or more.
Based on this, the prior art still has much room for improvement.
