Description

Air conditioner host with orthogonal air inlet surface and air outlet surface and equipment platform thereof

Technical Field

The invention belongs to the technical field of new energy, and particularly relates to an air conditioner host machine with an air inlet face and an air outlet face arranged in an orthogonal mode and an equipment platform of the air conditioner host machine.

Background

The heat of the air energy water heater is derived from air, the heat of the condenser of the air energy water heater is released, and the main body is the heat extracted from the air by the evaporator; the evaporator of the main machine of the water heater cannot effectively ventilate the ambient atmosphere, so that the air outlet of the evaporator is circularly short-circuited in the small space of the equipment platform, the temperature of the small space of the equipment platform is continuously reduced, and the evaporation pressure of the evaporator is further reduced, and the heating quantity is seriously attenuated; this phenomenon is more serious in low temperature seasons, and the heat pump main unit of the water heater is degenerated into an electric heating tube.

The pursuit of building designers, owners and society on the visual effect of the outer facade of the building causes the air conditioning host on the equipment platform to be hidden by the shutter of the outer facade, and the classical air conditioning host which enters from the back of the wind path and exits from the front of the wind path is blocked to exhaust the atmosphere outside the building, so that the heat exchange performance is seriously attenuated; the medium-speed exhaust (below 7 m/s) air conditioner host computer is hindered to the exhaust of the atmosphere environment outside the equipment platform, the static pressure of exhaust is increased, the exhaust speed is reduced, the air quantity is reduced, and a considerable part of air flow in the reduced exhaust air quantity is blocked by the shutter and returns to the equipment platform and is again inhaled by the external heat exchanger to cause air flow short circuit, so that the diffusion dilution effect of the exhaust penetrating through the shutter of the external elevation into the atmosphere environment is severely inhibited. The condensation pressure of the external heat exchanger is too high, the condensate is not enough in supercooling during the cooling operation in summer, the evaporation pressure of the external heat exchanger is too low, the circulation quantity of the refrigerant is greatly attenuated during the heating operation in winter, the task of the air conditioner serving as a heat carrier cannot be finished at full cost, and the performance of the air conditioner on an equipment platform is greatly reduced compared with laboratory data.

The two-carbon era comes, the popularization of the air energy water heater is greatly accelerated, and a household central air conditioner host and the air energy water heater become standard configurations on a fine room equipment platform in the eye; in summary, the classic household central air conditioner host and the air energy water heater in the early stage of the double carbon age have the following problems:

The air conditioning host and the air energy water heater host behind the outer facade shutter of the equipment platform are blocked from exhausting air to the atmosphere outside the building, the diffusion dilution effect of the air exhausted penetrating the outer facade shutter and entering the atmosphere is severely inhibited, so that the condensation pressure of the outer heat exchanger is too high, the condensate undercooling is insufficient when the air conditioning host is in refrigerating operation in summer, the evaporation pressure of the outer heat exchanger is too low, the circulation volume of the refrigerant is greatly attenuated when the air conditioning host is in heating operation in winter, the task of the air energy water heater of the air conditioner serving as a heat carrier cannot be completed at full scale, and the thermal performance of the air energy water heater of the air conditioning host on the equipment platform is greatly reduced compared with the laboratory data.

(2) Device resource reconfiguration

The air conditioner host and the air energy water heater host are vapor compression refrigeration equipment, the working principle is the same, the electromechanical structure is quite similar, and the air conditioner host and the air energy water heater host are a fluorine path system driven by a compressor, a condenser, a throttle valve and an evaporator, a fan and a water pump driven high-temperature heat source medium system and a low-temperature heat source medium system.

In a narrow equipment platform space, two sets of air conditioning hosts and heat pump hot water equipment which are mutually independent in physical principle and similar in structure are configured in this way, so that the air conditioning hosts and the heat pump hot water equipment are repeated configuration of refrigeration equipment resources and waste of the refrigeration equipment resources.

(3) Device platform inefficiency and inefficiency area increase

In the two-carbon era, a household central air-conditioning host machine and an air energy water heater (comprising a host machine and a water tank) have become standard configurations on a residential equipment platform;

as the air conditioning host, the air energy water heater and other devices on the residential device platform are required to be distributed as independent units, an air inlet channel is reserved for the outer heat exchanger arranged on the rear side of the air conditioning host adopting the back-in front-out side air outlet channel structure, and an air inlet channel and an air outlet channel are reserved for the air energy water heater host evaporator, the distance among the central air conditioning host, the air energy water heater host, the water tank and other devices on the device platform is increased, and the ineffective low-efficiency area is increased.

The air conditioner main unit of this embodiment is similar to embodiment 1, except that,

the exhaust outlet 31 is provided with a vertical strip rectangular outer convex exhaust section 35 which is matched with the shape of the exhaust outlet; a plurality of deflector plates 34 are arranged in the convex exhaust section 35.

The outer vertical surface shutter of the outer corridor type equipment platform 5 is provided with an opening structure 36 matched with the outer convex type exhaust section 35. The male air discharge section 35 is embedded in the opening structure 36 of the louver 52. When the air conditioner main unit is in operation, the exhaust air of the air outlet 31 passes through the opening structure of the louver 52 to be directly discharged to the ambient atmosphere.

in summer, hot air discharged by the outer heat exchanger of each layer of equipment platform diffuses and dilutes in front of the outer facade of the outer heat exchanger and partially flows back, the whole hot air discharged by the existing multi-layer equipment platform moves upwards and converges in a vertical direction, the hot air is connected end to end, beads are connected in a chain manner, the more the strings are, the outer facade of the equipment platform is covered, so that an air conditioning host of the upper layer of equipment platform sucks the hot air discharged by an air conditioning host of the lower layer of equipment platform, the condensation temperature is raised, the supercooling degree of condensate is reduced, and the refrigerating performance of the air conditioning host is deteriorated;

In this embodiment, under the constraint and induction of the flow guide plate group in the lateral exhaust section, the air after heat exchange of the air conditioning main machine in each layer flows to the outside space at the rear side of the compressor cavity at a high speed in the lateral direction, and the exhaust air flow is separated from the space right in front of the equipment platform, so that the exhaust air flow is stopped from flowing back to the local equipment platform, and the risk that the exhaust air flow is sucked by the lower adjacent equipment platform (winter) or by the upper adjacent equipment platform (summer) after being discharged from the local equipment platform is stopped.
