Description

A kind of air-breathing and it is vented mutually independent multicylinder compressor
Technical field
The invention mainly relates to low grade heat energies to utilize the big heat transfer temperature difference technical field of heat pumps with waste heat recycling, especially Air-breathing and the mutually independent multicylinder compressor of exhaust.
Background technique
Steam compression heat pump system can make full use of the waste heat of low grade heat energy, recycling building discharge, be a kind of Clean and effective energy conservation equipment, especially the key city in very cold area, effects of energy saving and emission reduction are especially apparent.For example, In North China's winter, about 20 DEG C of temperature of indoor exhaust when building is taken a breath, the temperature of bathroom bathing thermal wastewater is up to 30~35 ℃；On the other hand, it is that bath hot water is also required to biggish temperature promotion that outdoor fresh air, which introduces indoor, tap water heating, will be indoor Exhaust gas heat recycling can generate huge energy-saving and emission-reduction benefit for waste heat fresh air, the heat bath water of recycling waste water. Under the application of this kind of big heat transfer temperature difference, in order to effectively improve the Energy Efficiency Ratio and reliability of steam compression heat pump, fill Divide and recycles residual heat resources, a kind of multiple circuit heat pump system that heat exchange coil successively stacks of Chinese patent 201720269531.X System, the heat pump system are made of several independent heat pump circuits, and the heat exchange coil of each heat pump circuit is along fluid flow direction On be stacked together with being arranged successively.In this manner it is ensured that each heat pump circuit undertakes relatively uniform temperature rise, effective low promotion Its Energy Efficiency Ratio and reliability；On the other hand, it is successively stacked by heat exchange coil, air or water can produce biggish when flowing through Heat transfer temperature difference.
Above-mentioned multiple circuit heat pump system can make the heat pump system shape if each circuit uses independent compressor Size and weight are big, at high cost, are unfavorable for its popularization and application.It inhaled according to one, be vented independent multicylinder compressor, Ke Yiyou It solves the above problems to effect, still, there has been no suitable technical solution or products at present.
Summary of the invention
The purpose of the present invention is to mention for above-mentioned problems of the prior art for above-mentioned multiple circuit heat pump system For a kind of air-breathing compact-sized, light weight and cost is low and the mutually independent multicylinder compressor of exhaust.
In order to realize that above-mentioned goal of the invention, the technical solution adopted by the present invention are realized as follows: a kind of air-breathing and Be vented mutually independent multicylinder compressor, it is characterised in that: the multicylinder compressor include motor (1), main shaft (2), several solely Vertical cylinder, body (7), upper end cover (8), lower cover (9) and its intermediate bulkhead (10) etc.；Main shaft (2) is by base bearing (11) and auxiliary Bearing (12) support, main shaft (2) one end are connect with motor (1) rotor, and the other end is connected with lubricant passage way；All individual cylinders According to the intermediate position for being centainly regularly arranged on main shaft (2)；
All components of multicylinder compressor are placed in body (7), and body (7) bottom is equipped with mounting plate or support (13), the suction system of each compression unit of each individual cylinder and exhaust system depend on body and are equipped with and be connected with the external world Adapter tube or interface, main shaft (2), moving parts and compression assembly are compressed by the lubricating system feed lubrication configured in body (7) Unit is cooled down by working fluid or external fluid.
The top of individual cylinder is equipped with upper end cover (8), and lower part is equipped with lower cover (9), and middle interval is housed between individual cylinder Plate (10)；Main shaft (2) top is inserted at the rotor center of motor (1), and is supported by base bearing (11) and auxiliary bearing (12)； Main shaft (2) lower end is immersed in the oil sump of body (7) lower part；Upper end cover (8) outer rim and motor (1) stator outer rim are in close contact body (7) inner wall.
The quantity of individual cylinder is more than or equal to 2, and individual cylinder includes the first cylinder (3) to N cylinder, altogether N number of cylinder.
Exhaust valve in the exhaust system of each individual cylinder include valve block (101), limit plate (102), connector (103) and Supporting element (104), is sequentially overlapped arrangement between limit plate (102), valve block (101) and supporting element (104), connector (103) is solid It is scheduled on one end of limit plate (102), valve block (101) and supporting element (104), three is closely joined together.Supporting element (104) On have a gas vent, valve block (101) is elastic plate, and limit plate (102) is in tabular near through-hole, limit plate (2) it is another It holds upturned.
The first compression unit (31) for depending on the first cylinder (3) composition is driven by the first compression assembly (32) and first Component (33) composition, the first compression assembly (32) and the first cylinder (3) and its end cap or/and intermediate bulkhead etc. form independent pressure The operating room Suo Ji, driving assembly (33) are connect with main shaft (2) and the first compression assembly (32) simultaneously, are inhaled in operating room equipped with first Gas system (34) and first exhaust system (35)；
