Abstract
The utility model relates to a fast starting air conditioner which comprises a compressor, a four-way valve, a condenser, a throttle mechanism, an evaporator, an exhaust line, an air return line and an electrical control part. A by-pass balancing pressure mechanism is added between the exhaust pipe of the compressor and the air return pipe, and blocking mechanism are arranged on the exhaust pipe of the compressor and the throttle mechanism. When the operation powers off, the blocking mechanism on the compressor exhaust pipe cuts off the flow of cooling medium to prevent the cooling medium in a high-pressure side from flowing back to the compressor, the blocking mechanism on the throttle mechanism stops the cooling medium in the high-pressure side from flowing to a low-pressure side, and two mechanisms keep the pressure at high pressure side and the low pressure side of the system. When the air conditioner needs reboot, the by-pass balancing pressure mechanism operates firstly to balance the high pressure and the low pressure of both sides of the compressor, then the compressor fast starts up, and thus fast refrigeration (or heating) is realized. After the start of the compressor, the shutdown of the by-pass balancing pressure mechanism is delayed for a period of time in order to reduce starting load of the compressor. Thereby, small starting power is realized, and the impact to the electric network is relatively small.
Description
Technical field
The utility model technology relates to air regulator, after particularly a kind of shutdown, can start once more safely and fast, and realize refrigeration or the quick startup air-conditioner that heats fast.
Background technology
Air-conditioner producer all propagates the function that the air-conditioning of oneself producing has fast-refrigerating (heating) at present, but from having the structure and the system of air-conditioning now, does not have the function of this respect in fact.When indoor temperature reaches the air-conditioner design temperature, air-conditioner is shut down, during this period, indoor temperature probably departs from design temperature once more, compressor should start with recovery temperature immediately, but owing to will protect compressor, all will allow compressor stop opening after (purpose be allow the pressure balance of compressor both sides) in three minutes again, will cause the fluctuations in indoor temperature scope bigger like this, influence comfort level; And after three minutes, during compressor start because pressure is still very big, its moment starting power be more than 2 times of the normal operation of air-conditioner, so not only electrical network is impacted very greatly, compressor start is also impacted, often cause compressor to jump at once and stop.
The utility model content
The purpose of this utility model is intended to overcome the shortcoming that existing air-conditioning can not start fast, provide a kind of and can improve the compressor start environment, compressor can be started fast, make system set up high-pressure side and low-pressure lateral pressure fast, realize fast-refrigerating (or heating), and electrical network is impacted very little quick startup air-conditioner.
The technical scheme that realizes the utility model purpose is: the utility model comprises compressor, cross valve, condenser, throttle mechanism, evaporimeter, gas exhaust piping, return line and electric control system, increased bypass equalizing pressure mechanism between compressor exhaust pipe and muffler, a blocking-up mechanism is arranged on the compressor exhaust pipe and blocks mechanisms in series on throttle mechanism with another.
Bypass equalizing pressure mechanism between above-mentioned compressor blast pipe and the muffler can be the magnetic valve capillary of connecting, and also can be magnetic valve or electromagnetic expanding valve.
Blocking-up mechanism on the above-mentioned compressor blast pipe is check valve or magnetic valve.
Blocking-up mechanism on the above-mentioned throttle mechanism is two-way cut-off electromagnetic valve, or is made of with the unidirectional cut-off electromagnetic valve that head, tail link to each other with tail two statures.
The beneficial effects of the utility model are: in the course of work, when it is shut down from operation, blocking-up mechanism on the compressor exhaust pipe blocks refrigerant and flows, prevent that the coolant backflow in the high-pressure side from returning compressor, and the blocking-up mechanism that is connected on the throttle mechanism stops the refrigerant in the high-pressure side to continue to flow to low-pressure side, the two keeps the pressure of system high pressure and low-pressure side jointly, when air-conditioning need restart, bypass equalizing pressure mechanism is action earlier, quick balance compressor both sides high-low pressure, compressor starts fast then, has realized fast-refrigerating (or heating); Bypass equalizing pressure mechanism postpones a period of time and closes behind compressor start, reducing the compressor start load, thereby realize that starting power is little, impacts less relatively to electrical network.
Description of drawings
Fig. 1 is existing air-conditioner refrigeration (or heating) system schematic;
Fig. 2 is the utility model refrigeration (or heating) system schematic.
Omitted among the figure and other irrelevant parts of the present utility model point.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
As shown in Figure 1, existing common air-conditioning system forms a closed circuit by compressor 1, cross valve 4, condenser 5, throttle mechanism 7 (being capillary among the figure), evaporimeter 8; The similar existing common air-conditioning of the utility model system, as shown in Figure 2, it comprises compressor 1, cross valve 4, condenser 5, throttle mechanism 7, evaporimeter 8, the compressor air-discharging pipeline, return line and electric control system, unlike the prior art be between compressor 1 blast pipe and muffler, to have increased a bypass equalizing pressure mechanism 2 that forms by magnetic valve series connection capillary (this capillary does not draw in the drawings), a check valve 3 is set on compressor 1 blast pipe, two-way cut-off electromagnetic valve 6 of series connection on throttle mechanism 7, check valve 3 and two-way cut-off electromagnetic valve 6 all play the blocking-up loop.Magnetic valve in the bypass equalizing pressure mechanism 2 and the two-way cut-off electromagnetic valve 6 on the throttle mechanism 7 are all controlled by the electric control system of air-conditioner.
The utility model in the course of the work, when it was shut down from operation, the check valve 3 on compressor 1 blast pipe blocked refrigerant and flows, and prevents that the coolant backflow in the condenser 5 from returning compressor 1; And the two-way cut-off electromagnetic valve 6 of throttle mechanism 7 series connection stops the refrigerant in the condenser 5 to continue to flow to evaporimeter 8.When air-conditioning need restart, bypass equalizing pressure mechanism 2 action earlier, quick balance compressor 1 both sides high-low pressure, compressor 1 starts then, two-way cut-off electromagnetic valve 6 is opened with the unlatching of compressor 1 simultaneously, opening back tens seconds internal bypass equalizing pressure mechanisms 2 at compressor 1 just closes, the initial refrigerant of discharging of compressor has part directly to get back to muffler through bypass equalizing pressure mechanism 2, air-breathing refrigerant specific volume increases, thereby cause its starting power to descend, start rapidly, very little to the impact of electrical network, further improve the compressor start environment, realized fast-refrigerating (or heating).
The utility model just for single cold type, does not have cross valve 4 applicable to various air-conditioners such as single cold type, cold-warm type, the auxilliary patterns of fever of electricity.
