Abstract
The present invention relates to a self-adaptive variable throttling air conditioner which comprises a refrigeration system which is composed of a compressor, a condenser, an evaporator and a throttling device, wherein the throttling device is composed of a temperature or pressure detection element, a throttling controller and an adjustable throttling element. The pressure drop of the adjustable throttling element is adjusted by the throttling controller according to an environment or working condition signal detected by the temperature or pressure detection element to change the running state of the air conditioner, and the optimal system match at the temperature is realized. Compared with the prior art, the refrigeration system of the present invention is in the optimal match state due to the fact that the pressure drop of the throttling device can be adjusted in a self-adaptive mode under the condition of different working conditions. The seasonal energy efficiency ratio and the overloading capacity of the air conditioner can be enhanced.
Description
Technical field
The present invention relates to air-conditioner, particularly a kind of can be with the air-conditioner of environmental change adaptively changing system throttling arrangement.
Technical background
According to the refrigeration air-conditioner of steam compression type refrigeration circulation theory work, comprise domestic air conditioning, business air conditioner, central air-conditioning and vehicle air conditioning etc., to comprise compressor, condenser, throttling arrangement and four basic elements of character of evaporimeter at least.
For the air-conditioning system of under a definite operating mode, moving, when the air-conditioner refrigerating system Performance Match,, can make air-conditioner refrigerating efficiency under this operating mode the highest by refrigerant charge and throttle capillary tube length are adjusted, be called the optimal system coupling.Usually, the Optimum Matching of air-conditioner changes with operating condition, promptly has different optimum charging amount and capillary pipe length for different operating conditions.And usually said optimal system coupling is meant the regulation according to the room air conditioner national standard, does in the outside/35 ℃/24 ℃ of wet-bulb temperature and indoor do/the Optimum Matching result who obtains under the declared working condition condition of 27 ℃/19 ℃ of wet-bulb temperature.
The environment temperature of air-conditioner operation is actual to be constantly to change.According to the basic principle of contrary Carnot cycle, no matter whether air-conditioner refrigerating system is in Optimum Matching, when the outside environment temperature raise, the Energy Efficiency Ratio of air-conditioner refrigerating operaton all reduced; When the outside environment temperature reduced, the Energy Efficiency Ratio of air-conditioner refrigerating operaton all increased.But even refrigeration system reaches the optimal system coupling in declared working condition, when the outside environment temperature changed, air-conditioner was not in the optimal system coupling under this operating mode usually.
Estimate the energy-conservation level of air-conditioner and not only will examine the Energy Efficiency Ratio of air-conditioner under declared working condition, will consider that also air-conditioner at whole actual refrigerating efficiency with the cold season joint, promptly estimates with the index of seasonal energy efficiency ratio (seer).Obviously,, under other operating mode of examination seasonal energy efficiency ratio (seer), be not in the optimal system coupling, therefore be unfavorable for improving the seasonal energy efficiency ratio (seer) of air-conditioner if present air-conditioner is only considered the optimal system coupling under the declared working condition when design.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of air-conditioner self adaptation under different working conditions that can make to regulate throttling arrangement, make refrigeration system be in Optimum Matching, the air-conditioner of the seasonal energy efficiency ratio (seer) of raising air-conditioner and the adaptive variable throttling of capability of overload.
Purpose of the present invention can be realized by following technical proposals.
The present invention includes by compressor, condenser, the refrigeration system that evaporimeter and throttling arrangement are formed, throttling arrangement wherein is by temperature or pressure detecting element, throttling controller and adjustable restricting element are formed, its detecting element is a kind of mechanical type temperature-sensing element, as mercury or spring temperature sensor according to principle of expanding with heat and contracting with cold work, or change the temperature-sensitive bag of thermometric with saturated vapor pressure, adjustable restricting element is a kind ofly to control the temperature-sensing valve of its aperture size by displacement or pressure signal, or regulates the combination throttle part that temperature-sensing valve and capillary serial or parallel connection form by this.Temperature sensor is sent to throttling controller with the environment temperature that is detected with displacement or pressure signal, and throttling controller is also exported displacement or pressure signal control restricting element temperature-sensing valve valve opening, to be implemented in the optimal system coupling under this temperature.
The present invention compared with prior art because the pressure drop of energy self adaptation adjusting throttling arrangement under different working conditions makes refrigeration system be in Optimum Matching, can improve the seasonal energy efficiency ratio (seer) and the capability of overload of air-conditioner.
Description of drawings
Fig. 1 is a refrigeration system schematic diagram of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the specific embodiment of the present invention is described further.
As shown in Figure 1, refrigeration system of the present invention is connected to form successively by compressor 1, condenser 2, adjustable joint joint stream unit and evaporimeter 4.Adjustable joint joint stream unit is composed in series with capillary 13 by an assisted capillary 12 that is parallel with temperature-sensing valve 11.Temperature-sensing valve 11 can be two formula switch valves of a kind of temperature (or pressure) control.When the outdoor environment temperature that is detected when the temperature element 9 of temperature-sensing valve 11 was higher than design temperature, temperature-sensing valve 11 was in open mode, and assisted capillary 12 is had only 13 throttling actions of capillary by bypass; When the outdoor environment temperature that is detected when the temperature element 9 of temperature-sensing valve 11 was lower than design temperature, temperature-sensing valve 11 was in closed condition, and assisted capillary 12 and capillary 13 all play throttling action.By two kinds of different operating conditions of temperature-sensing valve 11 designs, can improve the Energy Efficiency Ratio of air-conditioner when underload, and strengthen the capability of overload of air-conditioner at high-load condition.
Above-mentioned temperature-sensing valve 11 also can adopt the control valve of a kind of temperature (or pressure) control.When the outdoor environment temperature that is detected when the temperature element 9 of temperature-sensing valve 11 raise, the aperture of temperature-sensing valve 11 increased, and the pressure of whole adjustable joint joint stream unit is fallen reduce; When the outdoor environment temperature that is detected when the temperature element 9 of temperature-sensing valve 11 lowered, the aperture of temperature-sensing valve 11 reduced, and makes the pressure of whole adjustable joint joint stream unit fall increase.Throttle part varies with temperature adaptive adjusting choke pressure drop, guarantees that air-conditioner all is in the optimal performance coupling under the varying environment condition, improved the seasonal energy efficiency ratio (seer) of air-conditioner.
