Description
Technical field
The application relates to a kind of low temperature and increases enthalpy type air-conditioner or Teat pump boiler.
Background technology
Common air-conditioner and Teat pump boiler include compressor, first heat exchanger, second heat exchanger and restricting element, be connected to form the heat-exchange working medium closed circuit by tube connector therebetween, the heat-exchange working medium that exhaust outlet of compressor is discharged high pressure enters first heat exchanger and condensation and release heat in first heat exchanger, the restricting element of flowing through again, the pressure of heat-exchange working medium reduces, the heat-exchange working medium that pressure is lower evaporates and absorbs heat after entering second heat exchanger, the heat-exchange working medium of low pressure flows back to the air entry of compressor again, discharges from exhaust outlet after the compressed machine pressurization again.There are following defective in existing air-conditioner and heat pump water-heating machine: its cooling or heating effect is limited by environment temperature, under at heating mode, if ambient temperature is low excessively, its performance degradation is very big, can't make system bring into play its due ability, this defective makes air-conditioner effectively to use at cold district, has limited its scope of application.
Summary of the invention
The application's purpose is to provide a kind of low temperature to increase enthalpy type air-conditioner or Teat pump boiler, the utility model has effectively overcome the influence of environment temperature, still can bring into play its due ability when environment temperature is low, can uses at north cold area, the scope of application is wider.
Its technical scheme is as follows:
A kind of low temperature increases enthalpy type air-conditioner or Teat pump boiler, comprises first heat exchanger, second heat exchanger, compressor, restricting element; Described compressor is provided with air entry, exhaust outlet and gas supplementing opening, this air-conditioner or Teat pump boiler also comprise flash vessel and blowdown pipe, described restricting element comprises first throttle element, second restricting element, first heat exchanger, first throttle element, flash vessel, second restricting element, second heat exchanger are connected to form refrigeration, heat pipeline by tube connector successively, this refrigeration, the two ends that heat pipeline are communicated with air entry, the exhaust outlet of compressor respectively, described blowdown pipe is located between flash vessel top and the compressor gas supplementing opening, is provided with the tonifying Qi control valve on blowdown pipe.
Because the utility model has been set up blowdown pipe, when environment temperature is crossed when low, can carry out tonifying Qi to the gas supplementing opening of compressor by blowdown pipe, than under the low ambient temperature, can effectively improve 15% to 25% refrigerating capacity, the cycle performance coefficient of heat pump also can improve 0.5 to 1.0, energy-saving effect is obvious, because heat pump can normally use under low temperature environment, goes for northern area, the scope of application is wider.
The application's further structure is:
Also be provided with balance port, dummy piston and compression chamber on the described compressor, balance port, compression chamber pass to the both sides of dummy piston respectively, and this balance port is communicated with the air entry of described compressor.The pressure of compressor air suction mouth conducts to balance port, and the pressure of balance port is lower than the compression chamber pressure inside, and piston moves to top, by gas supplementing opening compressor is carried out tonifying Qi; If add necessary valve, the time of control tonifying Qi that can be direct or indirect, as following two kinds of structures:
1, also be provided with balance port, dummy piston and compression chamber on the described compressor, balance port, compression chamber pass to the both sides of dummy piston respectively; This air-conditioner or Teat pump boiler also include balance cross valve and capillary, the high-pressure side of balance cross valve is communicated with the exhaust outlet of compressor, the low-pressure end of balance cross valve is communicated with the air entry of compressor by capillary, first switch terminal of balance cross valve is communicated with described balance port, and another switch terminal communicates with the air entry of compressor.If balance cross valve outage, dummy piston moves downward, and the blowdown pipe conducting is also carried out tonifying Qi to compressor, and on the contrary, if the energising of balance cross valve, dummy piston moves upward, and blowdown pipe is blocked, and stops to the compressor tonifying Qi.
2, also be provided with balance port, dummy piston and compression chamber on the described compressor, balance port, compression chamber pass to the both sides of dummy piston respectively; This air-conditioner or Teat pump boiler also include triple valve, and three ports of this triple valve are communicated with exhaust outlet, air entry and the balance port of compressor respectively.
With described tube connector that described exhaust outlet of compressor is communicated with on be provided with overheated outer tube, described blowdown pipe is two sections, is communicated with by first blowdown pipe, overheated outer tube, second blowdown pipe between described flash vessel top and the compressor gas supplementing opening.Because it is higher from the heat-exchange working medium temperature that exhaust outlet of compressor is discharged, can heat the heat-exchange working medium in the blowdown pipe by overheated outer tube, make heat-exchange working medium in the blowdown pipe be gaseous state as much as possible and enter into the compressor gas supplementing opening, can't become gaseous state by heating as the part heat-exchange working medium, also can be stored in overheated sleeve bottom.
This air-conditioner or Teat pump boiler also comprise cross valve, the air entry of described compressor, exhaust outlet, and described refrigeration, the two ends that heat pipeline are communicated with four ports of this cross valve respectively.Can change the flow direction of the heat-exchange working medium of first heat exchanger of flowing through, second heat exchanger easily by this cross valve, with this realize freezing, the transformation of heating mode.
Described tonifying Qi control valve is magnetic valve or expansion valve.
