Abstract: 0bjective To improve the animal welfare and overcome the limitations of warming methods used in non—human primate laboratory animals，this article introduces an automatic system for warming monkey house． Methods This system uses a reverse Carnot cycle principle，makes air heat pump water heater as a heating source，inputs hot water through galvanized iron pipes to each monkey room．On one hand，it can directly dissipateheat．On the other hand，it can be treated as a jumping climbing frame for monkeys．Results Because the temperature of the facility was kept at about 40℃in winter．monkeys are used to playing and sleeping on it．The morbidity and mortality are significantly decreased compared with the same season of last years．Meanwhile，the natality and survival are increased．Conclusion This automatic system is dimentional levels，temperature constant and controllable．As it is observed，there are obvious advantages，such as effective warming，high efficiency， environmental protection，and resources saving．
