An air conditioner host is arranged on the fine room equipment platform, and an air energy water heater is also arranged at the same time, as shown in figure 1. In the current real smart dress room project, the mounting position of air can water heater host computer and water tank on equipment platform is very random, basically meets the seam pin, and the more unlikely problem to the environment ventilation of water heater host computer heat absorption evaporimeter of solving.
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.
As shown in fig. 2, 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 outer facade louver, and the classical air conditioning host entering from the back of the wind path and exiting from the front of the wind path is blocked to seriously attenuate the air exhaust and heat exchange performance of the atmosphere outside the building; 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.

(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 water heaters which are physically independent and have the same principle and similar structure are integrated with a host machine and heat pump water heating equipment, so that repeated allocation of refrigeration equipment resources is realized, and waste of the refrigeration equipment resources is realized.
(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.
