Description

An energy-saving air conditioner

technical field

The utility model relates to the technical field of air conditioning, in particular to an energy-saving air conditioner.

Background technique

Some special environmental areas require air conditioners to work all year round to provide cooling for equipment. Completely rely on the compression refrigeration method to cool down, the energy efficiency is low throughout the year, and it does not meet the requirements of energy conservation and emission reduction advocated by the state. In the case of low outdoor ambient temperature, by measuring the indoor and outdoor temperature and humidity conditions, when the temperature and humidity conditions are met, the outdoor low-temperature fresh air is directly introduced to cool down, and there is no need to turn on the compressor, which greatly improves energy efficiency.

When the fresh air is running, the common practice is that the cold air introduced is completely isolated from the hot indoor air before being sent into the room without mixing. It is easy to generate condensed water, which will cause a short circuit of the power supply, resulting in equipment failure or disaster; insufficient air convection will result in poor cooling effect.

For the integral fresh air conditioner, the evaporator is usually placed at an angle, which brings disadvantages: both compressed refrigeration and fresh air mode air will pass through the evaporator. Due to the poor cleanliness of the outdoor air, the evaporator is easily dirty and blocked; The evaporator is placed obliquely, so the size of the flap space cannot be effectively used, and the overall size of the unit will be larger. Generally, the integrated energy-saving air conditioner simply integrates the functions of mechanical refrigeration and fresh air replacement, so as to realize the coexistence of the air conditioning system and the fresh air system. However, the limitation on the size of the unit at the installation site is ignored, and the integrated unit cannot perform well in the mode of air-conditioning refrigeration and fresh air replacement, resulting in that the energy efficiency of the air conditioner has not been improved very well.

Due to the differences in site structure and equipment, the structural requirements for integral energy-saving air conditioners are also quite different. The air outlet mode of the existing integrated energy-saving air conditioner is fixed and cannot be adjusted according to needs, and the applicability is not comprehensive enough.

The existing integrated energy-saving air conditioners usually add a filter in the fresh air channel in the fresh air mode. When switching to the compression cooling mode, the filter is still in the indoor channel, which increases the indoor circulation air resistance and increases the power consumption of the fan. , the energy efficiency of the compression refrigeration mode is reduced, and the maintenance cycle of the filter screen is shortened.

Utility model content

A. The utility model can make better use of the limited space of the unit and ensure the smooth air flow of the unit by making a reasonable structural layout of the positions of each device. The utility model places the evaporator at the indoor air inlet. When the fresh air mode is turned on, the air flow does not pass through the evaporator, which avoids the increased air resistance caused by the air flow passing through the evaporator, so that the fresh air mode has higher energy efficiency.

B. When changing the fresh air function, a filter is usually added in the air inlet channel, but when switching to the air-conditioning mode, the filter is still in the channel, which increases the resistance of the air circulation and reduces the energy efficiency of the air-conditioning mode. The utility model forms a component by combining the filter screen and the air valve, and the filter screen is opened or closed with the switching of the air valve, that is, the filter screen is opened with the air valve in the fresh air mode, and the air entering the base station from the outside world passes through the filter. To achieve the purpose of filtering; and when the fresh air mode is off, the filter is closed with the air valve to reduce the air circulation resistance.

C. This utility model successfully solves the problem of maintaining the condenser of the integral energy-saving air conditioner. By reserving a maintenance space under the condenser, the cleaning water collector can be placed under the condenser during maintenance, and the condenser can be washed with water The waste water generated during the operation is collected and discharged through the collector to avoid water damage to the unit and provide compression refrigeration energy efficiency.

D. In this utility model, an actuator is installed at the rotating shaft of the air door, and the controller automatically controls the actuator according to the set logic through the parameter collection of the indoor and internal temperature and humidity sensors. In the fresh air mode, according to the outdoor temperature and humidity conditions, open the switching air valve to the appropriate position; in other modes, switch the switching air valve to the closed position.
