Abstract
The utility model relates to a capacity unloading device of a multi-connected air conditioner, including an air conditioner outdoor heat exchanger. Wherein part of the air conditioner outdoor heat exchangers are connected with a refrigerant diffluence loop which is formed by connecting in series an electromagnetic valve and capillary tubes, one end of the electromagnetic valve is connected with the air conditioner outdoor heat exchanger, the other end of the electromagnetic valve is connected with one end of the capillary tubes, the other end of the capillary tubes is connected with refrigerant inlets of part of the air conditioner outdoor heat exchangers, refrigerant outlets of part of the heat exchangers are connected with a compressor loop. The refrigerant diffluence loop of the utility model which is formed by connecting in series the electromagnetic valve and the capillary tubes can shunt small part of refrigerants which are cooled from the air conditioner outdoor heat exchanger, the small part of refrigerants are delivered to the compressor loop after being evaporated by few heat exchangers of the outdoor heat exchangers, thereby part of the capacity is unloaded when an inner motor with small power is running, and a normal matching relationship between the compressor and the inner motor capacity is obtained. The utility model not only can unload part of the capacity of the system effectively, makes the multi-connected air conditioner operate normally when the inner motor with small power is running, and makes the system operate safely and stably, but also the control is simple, the cost is low, and the device is safe and reliable.
Description
Technical field
The utility model is a kind of ability discharge mechanism of multi-connected air conditioner, belongs to the renovation technique of the ability discharge mechanism of multi-connected air conditioner.
Background technology
Capacity changeable multi-link formula air-conditioning has two kinds of connected formula air-conditioning and digital multi-connected air conditioners at present, for connected formula air-conditioning, in order to guarantee the safe and reliable running of compressor, the running frequency of frequency-changeable compressor all has a reasonable range, its general low-limit frequency is all more than 60Hz, for very little load, for example singly open the interior mechanism of 0.8HP when cold, the ability that the minimum operation frequency of compressor is exported also substantially exceeds the interior needed ability of machine, there is same problem for digital multi-connected air conditioner, if untimelyly in this case uninstall unnecessary ability, air-conditioning system just can not normally be moved, even damages compressor.
The utility model content
The purpose of this utility model is to consider the problems referred to above and a kind of unnecessary ability that can in time uninstall is provided, and air-conditioning system can normally be moved, and avoids damaging the ability discharge mechanism of the multi-connected air conditioner of compressor.The utility model control is simple, and cost is low, and is safe and reliable.
The technical solution of the utility model is: include outdoor heat exchanger of air conditioner, wherein be connected with by magnetic valve in the part heat exchanger of outdoor heat exchanger of air conditioner and be connected in series the coolant distribution loop that forms with capillary, one end of magnetic valve is connected with outdoor heat exchanger of air conditioner, the other end of magnetic valve is connected with an end capillaceous, the other end capillaceous is connected with the refrigerant inlet of the part heat exchanger of outdoor heat exchanger of air conditioner, and the refrigerant exit of part heat exchanger is connected with compressor loop.
The utility model is owing to adopt by one section capillary of magnetic valve connection, be connected to the structure of a little heat exchanger of outdoor heat exchanger of air conditioner, magnetic valve is connected in series the coolant distribution loop that forms and can shunts from the cooled small part refrigerant of outdoor heat exchanger of air conditioner with capillary, deliver to compressor loop after a little heat exchanger evaporation through outdoor heat exchanger, thereby uninstall the part ability when reaching out in little the number machine, allow compressor and interior function power reach normal matching relationship.The utility model not only can effectively uninstall the part ability of system, allows multi-connected air conditioner run well in the machine in opening little number, makes security of system stable operation, and control is simple, cost is low, safe and reliable.The utility model is that a kind of design is ingenious, function admirable, the ability discharge mechanism of convenient and practical multi-connected air conditioner.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
Embodiment:
Schematic diagram of the present utility model as shown in Figure 1, include outdoor heat exchanger of air conditioner 1, wherein be connected with in the part heat exchanger 11 of outdoor heat exchanger of air conditioner 1 and be connected in series the coolant distribution loop that forms with capillary 3 by magnetic valve 2, one end of magnetic valve 2 is connected with outdoor heat exchanger of air conditioner 1, the other end of magnetic valve 2 is connected with an end of capillary 3, the other end of capillary 3 is connected with the refrigerant inlet of the part heat exchanger 11 of outdoor heat exchanger of air conditioner 1, and the refrigerant exit of part heat exchanger 11 is connected with compressor loop.
In the present embodiment, part heat exchanger 11 is a little several U type pipe.
Operation principle of the present utility model is as follows: multi-connected air conditioner is in opening little number in the machine, magnetic valve 2 is connected in series the coolant distribution loop that forms and can shunts from outdoor heat exchanger of air conditioner 1 cooled small part refrigerant with capillary 3, deliver to compressor loop after part heat exchanger 11 evaporations through outdoor heat exchanger 1, thereby uninstall the part ability when reaching out in little the number machine, allow compressor and interior function power reach normal matching relationship.
