Description
Technical field
The present invention relates to technical field of heat pumps, and in particular to a kind of changes in temperature double purpose air screw source heat pump.
Background technique
Air source heat pump is a kind of energy saver for making heat flow to from low level heat energy air high-order heat source using high potential.
It is a kind of form of heat pump.As its name suggests, heat pump, can be the Lowlevel thermal energy that cannot directly utilize namely as pump
(heat as contained in air, soil, water) is converted to utilizable high level heat, saves part high potential to reach
The purpose of (such as coal, combustion gas, oil, electric energy).
Air source heat pump has been widely applied as a kind of energy-saving and environment-friendly heating system in different heating places.Air
The compressor of source heat pump mainly has centrifugal, vortex and three kinds of screw at present, and the occasion that it is applied according to reapective features is not
It is identical to the greatest extent.Air-source screw compressor hot-water heating system is particularly suitable for the concentration of middle and small burn coal boiler entire building formula
The improvement project of heating system, unit placement location is flexible, can arbitrarily be adjusted according to system size, regulates and controls simple and convenient.
Existing air source heat pump system is easy to cause the system failure in the presence of easy frosting, the thermal efficiency are low in low temperature environment
The problems such as.Publication No.: CN201503134U is disclosed a kind of " double pressure air friction drags ", and major function is to realize
Gaseous refrigerant passes through two second compression of low-pressure stage compressor and high pressure stage compressor, and compression efficiency is greatly improved, and guarantees double
The operation for pressing air friction drag stable in low temperature environment.Publication No. CN204806738U discloses " the big temperature difference
Screw two-stage condensation device air source heat pump heats unit ", provide it is a kind of improve compression ratio using two compressors, reduce every
The work of compressor runs intensity, the failure of less system, and the temperature for producing hot water can be improved by secondary temperature elevation.Again
Such as, Chinese patent 200710013207.2 discloses a kind of air friction drag, and main technical points are, first,
Outdoor temperature signal is reached into a controller and setting temperature by the parallel connection of at least two compressors, and by a temperature sensor
Angle value is compared, and the unlatching quantity of compressor is then determined according to comparison result；Second, setting detection suction pressure of compressor
Pressure sensor, the pressure value measured is compared with setting value, and is to be turned up or drop according to comparison result determination
Low rotation speed of fan；Third, increasing connection air duct and circulating chilled water device.
But these disclosed technologies there is problems when in use:
1, device integration is lower, and structure is complicated, and equipment price is expensive, and mobile and placement/placement is very inconvenient, exists,
The problems such as noise is big, and vibration is big, and water circulating pump freezes when intermittent duty, in addition, after water tank topped up with water inside air source heat pump,
There can be very big pressure to idler wheel, it is long-term to use in this way, idler wheel service life can be made to be greatly lowered, after idler wheel damage, family
It is possible to topple over Integral air source heat pump, there are security risks；
2, work conversion ratio is not high enough, and heating and refrigeration effect be not good enough, and energy-saving effect is bad, and operating power adjusts inconvenient
Deng；
3, to the bad adaptability of working environment, environment temperature is too low, and (work component surface is easy icing frosting etc., causes
Damage) or excessively high (heat dissipation of work component not in time, is easy to cause damage) all have a great impact to it, and environment temperature mistake
Low heating effect will have a greatly reduced quality, or even not be able to satisfy people to the needs of hot water or heat supply.
