Abstract
The utility model provides an ultralow-temperature air source heat pump unit system which comprises an evaporator, a condenser, a compressor, a four-way valve and a first expansion valve, wherein the evaporator, the condenser, the compressor and the expansion valve are connected by the four-way valve. The ultralow-temperature air source heat pump unit system is characterized in that the compressor is a low-temperature enhanced vapor injection compressor, and the condenser is connected with the compressor through an economizer and a capillary tube which are additionally arranged between the condenser and the compressor to form an air supply enhanced vapor circuit. The ultralow-temperature air source heat pump unit system can adapt to cold low-temperature environments, and an air conditioning heat pump unit can be effectively used in a severe cold area needing heating.
Description
Technical field
The machine set system of this reality novel machine set system that relates to a kind of air source heat pump, particularly a kind of ultra-low temperature air source heat pump.
Background technology
The air conditioner and heat pump unit of existing use; be lower than subzero 5 when spending in environment temperature; heating effect is very poor, and Energy Efficiency Ratio does not also reach 1.0, even can not heat; air conditioner and heat pump unit is especially when arctic operation; because evaporating temperature is very low, the low pressure of system is very low, and the compression ratio of unit is too large; be easy to the press overtemperature protection, air conditioner and heat pump unit can not be moved at severe cold area at all.So, needing most the severe cold area of heating, the common air-conditioning source pump is to can not get good application.
Summary of the invention
Effective use for the air conditioner and heat pump unit that realizes severe cold area, improve practicality and the usability of product, the utility model provides a kind of ultra-low temperature air source heat pump machine set system, system comprises evaporimeter, condenser, compressor, cross valve, expansion valve one, consisted of by cross valve connection evaporimeter, condenser, compressor, expansion valve one, it is characterized in that: described compressor is to adopt the low-temperature air injection enthalpy increasing compressor, be provided with economizer in addition between described condenser, the compressor, capillary connects, form tonifying Qi and increase the enthalpy loop.
Described economizer is provided with magnetic valve one in addition, expansion valve two is controlled.
Described capillary is provided with in addition magnetic valve two and controls.
After adopting said structure, refrigerant is by opening magnetic valve one and expansion valve two enters economizer, heat absorption flashes to gas, enter the press intermediate cavity by gas supplementing opening, improve the press capacity, increase the press input power, reduce compression ratio, improve the stability that system moves under low temperature environment, opened magnetic valve two at delivery temperature Gao Shike and carry out capillary system is carried out fluid infusion, reduced rapidly delivery temperature, when can be implemented in-25 ℃, this system can also run well, and having realized is needing the severe cold area of heating, can effectively the using of air conditioner and heat pump unit.
Description of drawings
Fig. 1 is the utility model system architecture schematic diagram.
Be denoted as among the figure: 1 evaporimeter, 2 condensers, 3 compressors, 4 cross valves, 51 expansion valves one, 52 expansion valves two, 6 economizers, 7 capillaries, 81 magnetic valves one, 82 magnetic valves two.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is described in further detail, but does not consist of any restriction of the present utility model.
As shown in Figure 1:
A kind of ultra-low temperature air source heat pump machine set system, system comprises evaporimeter 1, condenser 2, compressor 3, cross valve 4, expansion valve 1, consisted of by cross valve 4 connection evaporimeters 1, condenser 2, compressor 3, expansion valve 1, it is characterized in that: described compressor 3 is to adopt the low-temperature air injection enthalpy increasing compressor, be provided with in addition economizer 6 between described condenser 2, the compressor 3, capillary 7 connects, form tonifying Qi and increase the enthalpy loop.
Economizer 6 is provided with magnetic valve 1 in addition, expansion valve 2 52 carries out controlling run.
Capillary 6 is provided with in addition magnetic valve 2 82 and carries out controlling run.
In the relatively lower use of environment temperature, evaporating temperature descends, evaporating pressure descends, the press return-air reduces, input power diminishes, and compression ratio increases, and utilizes an economizer 6, when low temperature, refrigerant is by opening magnetic valve 1 and expansion valve 2 52 enters economizer 6, and heat absorption flashes to gas, enters press 3 intermediate cavity by gas supplementing opening, improve compressor 3 capacities, increase compressor 3 input powers, reduce compression ratio, improved the stability that system moves under low temperature environment, the simultaneously utilization of economizer 6 can improve the Energy Efficiency Ratio of system greatly, through this system of experiment when the environment temperature-15 ℃, when 5 ℃ of inflow temperatures, 45 ℃ of leaving water temperatures, main frame runs well, and heating energy efficiency ratio reaches more than 2.0.
Open magnetic valve 2 82 at delivery temperature Gao Shike and realize that 7 pairs of systems of capillary carry out fluid infusion, reduce rapidly delivery temperature, this system can adapt to colder environment like this, through limit test, in the time of-25 ℃, this system can also run well, and having realized is needing the severe cold area of heating, can effectively the using of air conditioner and heat pump unit.
The utility model can effectively use at low temperature environment, has improved usability and the practicality of product.
