Abstract
The utility model discloses a household air conditioner capable of realizing low-temperature heating, comprising a high-temperature grade refrigerating system and a low-temperature grade refrigerating system. The high-temperature grade refrigerating system consists of a high-temperature condenser, a capillary tube, a high-temperature evaporator and a high-temperature grade compressor, which are connected end to end in sequence; the low-temperature grade refrigerating system consists of a condensing evaporator, a capillary tube, a low-temperature evaporator and a low-temperature compressor, which are connected end to end in sequence; and a switching device is further connected between the high-temperature grade refrigerating system and the low-temperature grade refrigerating system, and when the environment temperature is lower than minus 20 DEG C, the switching device connects the condensing evaporator as a substitute for the high-temperature evaporator into the high-temperature grade refrigerating system. The utility model aims at providing the household air conditioner which can realize cascade type low-temperature heating.
Description
[technical field]
But the utility model relates to a kind of domestic air conditioning of low-temperature heating.
[background technology]
When being 7 ℃, tests the tangible outdoor environment temperature of heating capacity of common domestic air conditioning nominal, temperature is low more, the heating capacity decay is severe more, general domestic air conditioning can only guarantee can normally move more than-7 ℃, but heating capacity output has only about 20% of specified heating capacity, and frequent defrosting, can't be to the indoor heat that provides.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, and a kind of domestic air conditioning of realizing the superposition type low-temperature heating is provided.
For achieving the above object, the utility model has adopted following technical proposal:
But a kind of domestic air conditioning of low-temperature heating includes high temperature level refrigeration system and low temperature level refrigeration system, and described high temperature level refrigeration system is connected to form in turn by high temperature condenser, capillary, high-temperature evaporator, high temperature stage compressor from beginning to end; Described low temperature level refrigeration system is connected to form in turn by condenser/evaporator, capillary, cryogenic vaporizer, low temperature stage compressor from beginning to end; Between high temperature level refrigeration system and low temperature level refrigeration system, also be connected with switching device shifter, replace high-temperature evaporator to be linked in the high temperature level refrigeration system condenser/evaporator when this switching device shifter is lower than-20 ℃ in environment temperature.
Described switching device shifter comprises 2 magnetic valves with three interfaces, and a magnetic valve is connected between high-temperature evaporator and the capillary, and the 3rd interface of this magnetic valve is connected with an interface of condenser/evaporator; Another magnetic valve is connected between high-temperature evaporator and the high temperature stage compressor, and the 3rd interface of this magnetic valve is connected with another interface of condenser/evaporator.
Compared with prior art, the beneficial effects of the utility model are:
1, this air-conditioning adopts the cascade refrigeration system, and high temperature level and low temperature level system carry out heat exchange by condenser/evaporator, guarantees that the two poles of the earth refrigeration system can both normally move, and makes this air-conditioning can guarantee under-20 ℃ outdoor temperature that 50% heat of specified heating capacity exports.
2, this air-conditioning parts are few, and volume is little, and are simple to operate, and cost is low.

Fig. 1 is a block diagram of the present utility model;
Fig. 2 is a R410A pressure-enthalpy chart of the present utility model.
[specific embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
Referring to Fig. 1, but a kind of domestic air conditioning of low-temperature heating includes high temperature level refrigeration system and low temperature level refrigeration system, and described high temperature level refrigeration system is connected to form in turn by high temperature condenser, capillary 1, high-temperature evaporator, high temperature stage compressor from beginning to end; Described low temperature level refrigeration system is connected to form in turn by condenser/evaporator, capillary 1, cryogenic vaporizer, low temperature stage compressor from beginning to end; Between high temperature level refrigeration system and low temperature level refrigeration system, also be connected with switching device shifter, replace high-temperature evaporator to be linked in the high temperature level refrigeration system condenser/evaporator when this switching device shifter is lower than-20 ℃ in environment temperature.
Described switching device shifter comprises that 22, one magnetic valves 2 of magnetic valve with three interfaces are connected between high-temperature evaporator and the capillary, and the 3rd interface of this magnetic valve 2 is connected with an interface of condenser/evaporator; Another magnetic valve 2 is connected between high-temperature evaporator and the high temperature stage compressor, and the 3rd interface of this magnetic valve 2 is connected with another interface of condenser/evaporator.
The 3rd interface of described magnetic valve is connected with condenser/evaporator by copper pipe.
When outdoor environment temperature is higher, has only the operation of high temperature level refrigeration system, with general pump type heat domestic air conditioning; When outdoor environment temperature very low (about 20 ℃), the cold-producing medium of high temperature level no longer flows through high-temperature evaporator by the control of magnetic valve but flows into condenser/evaporator, simultaneously, low temperature level refrigeration system starts, low temperature level refrigeration system can be finished kind of refrigeration cycle at-20 ℃, and in condenser/evaporator place release heat; High temperature level and low temperature level are carried out heat exchange in condenser/evaporator, the evaporating temperature that has guaranteed high temperature level refrigeration system still about 0 ℃, has guaranteed the normal operation of system, thereby realize the superposition type low-temperature heating.
