Abstract
The utility model discloses an air source heat pump system of an automatic cooling of a compressor, which belongs to the field of air source heat pumps. The system comprises the compressor, a condenser, an expansion valve, and an evaporimeter which are sequentially connected in the closed loop manner, wherein a temperature sensor is arranged on an outlet pipeline of the compressor; a throttling hydrojet component is connected onto a pipeline at the front of the expansion valve in a bypass manner; an outlet end of the throttling hydrojet component bypasses the expansion valve and the evaporimeter and is connected onto an inlet pipe of the compressor; the opening degree of a liquid flow channel of the throttling hydrojet component is corresponding to the detection temperature of the temperature sensor. According to the utility model, when the system works, the motion of the throttling hydrojet component is controlled through a control system, so as to allow partial condensated liquid to directly mix with gases coming from an outlet of the evaporimeter, and then enter into the compressor; the outlet temperature of the compressor is enabled to be in a set safety range, so that damages for the compressor caused by over high exhausted temperature of the compressor is not caused, and the heating capacity is improved; therefore, the work efficiency, stability, and economical efficiency of the overall machine system are improved. The system is suitable for the field of heat pump water heaters.
Description
Technical field
The utility model relates to a kind of heat pump assembly, particularly a kind of heat pump apparatus of air source.
Background technology
air source heat pump system of the prior art is mainly by compressor, condenser, expansion valve and evaporimeter are connected to form by refrigerant tubing, heat pump is when making heating operation, after being sucked by compressor, the refrigerant gas of low-temp low-pressure becomes the refrigerant gas of HTHP, the refrigerant gas of HTHP is heat release and the liquid that congeals in condenser, correspondingly, coolant temperature in condenser raises, but outward supplying heat, condensed refrigerant liquid becomes the gas of low-temp low-pressure again through the evaporation of absorbing heat after the expansion valve reducing pressure by regulating flow and in evaporimeter, evaporimeter is set directly in air, can absorb heat from the outside air environment, the refrigerant gas of low-temp low-pressure again enters compressor and compresses, circulation and so forth, by the continuous outward supplying heat of condenser.
Its weak point is: under the operating mode of producing high-temperature-hot-water, because the coolant water temperature in condenser constantly raises, cause compressor pressure reduction than excessive, and then cause the import inspiratory capacity of compressor to reduce, and then cause compressor exhaust temperature too high, and make the compressor lubricant oil charing and cause compressor dry grinding, burn out compressor, not only affect the reliable and stable long journey of source pump, and caused the maintenance waste.
The utility model content
The purpose of this utility model is to provide a kind of air source heat pump system of compressor automatic cooling, compressor exit temperature can be controlled in certain temperature range.
The purpose of this utility model is achieved in that the air source heat pump system of compressor automatic cooling, the compressor, condenser, expansion valve and the evaporimeter that comprise closed loop connection successively, described compressor outlet pipeline is provided with temperature sensor, on pipeline before described expansion valve, bypass is connected with the throttling liquid ejection element, the port of export of described throttling liquid ejection element walks around expansion valve and evaporimeter is connected on the inlet tube of compressor, and the aperture of the fluid course of described throttling liquid ejection element is corresponding with the detected temperatures of described temperature sensor.
during the utility model work, after being sucked by compressor, the refrigerant gas of low-temp low-pressure becomes the refrigerant gas of HTHP, the refrigerant gas of HTHP is heat release and the liquid that congeals in condenser, condensed refrigerant liquid becomes the gas of low-temp low-pressure again through the evaporation of absorbing heat after the expansion valve reducing pressure by regulating flow and in evaporimeter, the refrigerant gas of low-temp low-pressure again enters compressor and compresses, when hygrosensor detects compressor exit temperature when higher, it controls the liquid ejection element action by control system, make liquid after partial condensation without evaporator evaporation directly the gas with evaporator outlet mix, in the process of mixing, the liquid evaporation heat absorption, reduced the delivery temperature of compressor, the outlet temperature of compressor is in the safe range of setting, compressor exhaust temperature is too high makes the refrigeration oil charing cause compressor to burn out thereby can not cause, perhaps cause the compressor liquid hammer, perhaps compressor internal lubrication oil is washed out and cause the compressor dry grinding.And in high pressure ratio compression situation, increased the internal circulating load of unit, improved heating capacity; And then improved the operating efficiency of whole machine set system, and stability, economic and practical.This device applied heat pump water heater field.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 temperature sensor, 2 condensers, 3 expansion valves, 4 compressors, 5 evaporimeters, 6 throttling liquid ejection elements.
The specific embodiment
as shown in the figure, air source heat pump system for the compressor automatic cooling, its structure mainly comprises the compressor 4 of closed loop connection successively, condenser 2, expansion valve 3 and evaporimeter 5, particularly, the outlet of compressor 4 connects the import of condenser 2, the outlet of condenser 2 connects the import of expansion valve 3, the outlet of expansion valve 3 connects evaporimeter 5 imports, evaporimeter 5 outlets connect the import of compressor 4, compressor 4 outlet conduits are provided with temperature sensor 1, on pipeline before expansion valve 3, bypass is connected with liquid stream liquid ejection element 6, the port of export of liquid stream liquid ejection element 6 walks around expansion valve 3 and evaporimeter 5 is connected on the inlet tube of compressor 4, the aperture of the fluid course of liquid stream liquid ejection element 6 is corresponding with the detected temperatures of described temperature sensor 1, this corresponding relation is realized by control module, be that temperature sensor 1 passes to control module with signal, control the aperture of the fluid course of liquid stream liquid ejection element 6 through control module, when compressor 4 outlet temperatures raise, the aperture of the fluid course of liquid stream liquid ejection element 6 increases, temperature is higher, aperture is larger, when compressor 4 outlet temperatures reduced, the aperture of the fluid course of liquid stream liquid ejection element 6 reduced, and temperature is lower, and aperture is less, and above-mentioned throttling liquid ejection element 6 can be the adjustable choke valve of aperture, can be also some capillaries that can turn-off one by one.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
