Temperature controller of hydrogen storage alloy cooling and heating air conditioner and its control method

Abstract

The present invention relates to the temperature controller and control method of hydrogen storage alloy cooling and heating air conditioner. The temperature controller includes the temperature sensors set on the indoor exhaust pipe and the outdoor exhaust pipe and connected to the control part. The temperature control method includes the following steps: setting required air conditioning temperature range; judging in the control part whether the temperature of the exhausted air to excess the set range; and turning the air temperature regulating valve to change over the flow channel properly to obtain air in the required temperature via the mixing of cold air and hot air. The present invention can maintain the indoor temperature in the required range.

Description

technical field [0001] The invention relates to a hydrogen storage alloy cooling and heating air conditioner, in particular to a temperature control device and a control method for a hydrogen storage alloy cooling and heating air conditioner. Background technique [0002] General hydrogen-storage alloy cooling and heating air conditioners use the reaction heat generated by the compressor to move hydrogen from one side of the reactor to the other side of the reactor or in the opposite direction to maintain a certain temperature in the indoor space. [0003] Such as figure 1 The shown cooling and heating air conditioner is mainly composed of a first reactor 10, a second reactor 20, a hydrogen flow pipe 31, a compressor 32, an air duct 34 for inflow guidance, an air regulating valve 35 for flow channel switching, and an air supply device 37. composition. [0004] The above-mentioned first reactor 10 and second reactor 20 are arranged correspondingly inside the main body, and ...

Problems solved by technology

However, as the hydrogen storage alloy 11, 21 charged inside the reactor prolongs the absorption or release time of hydrogen, the heating performance and heat absorption performance of the reactor will gradually decrease, and the efficiency of the reactor will gradually decrease. In order to ensure The normal and effective operation of the heating and cooling air conditioner has to install a reactor with a larger capacity than the actual capacity

In addition, the temperature of the air discharged into the room is controlled by adjusting the flow rate of hydrogen, so it takes a long time to adjust the temperature of the discharged air, and the variation range of the temperature of the air discharged into the room is increased.

like figure 2 As shown, with the increase of the temperature range of the air discharged into the room, the maintenance of the desired temperature set by the user is limited, and the refinement of the desired temperature set by the user is also limited.
