Abstract

The invention discloses an efficient total heat recovery central air conditioner which comprises a heat recovery and exchange system, a compression motor, a chilled water temperature sensor, a pressure water pump, a condenser, a temperature and humidity sensor and an integrated chip. The heat recovery and exchange system comprises a heat exchanger and a fan arranged on one side of the heat exchanger, and the heat exchanger is provided with a water inlet and a water outlet. According to a refrigerant control method of the efficient total heat recovery central air conditioner, refrigerants in the efficient total heat recovery central air conditioner is automatically adjusted, the phenomena that condensate depression does not exist at the upstream position of a throttling device of the efficient total heat recovery central air conditioner, and low-pressure protection of part of a heat recovery and exchange unit occurs when the ambient temperature is high and the water inlet temperature of the heat-recovery heat exchanger is low are avoided, and the operation range of the efficient total heat recovery central air conditioner is obviously expanded. Moreover, when the water inlet temperature of the heat-recovery heat exchanger is low and the ambient temperature is low, the condensing temperature and exhaust temperature of the efficient total heat recovery central air conditioner are increased forcedly, the heat exchange capacity of the heat-recovery heat exchanger is enhanced, and it is guaranteed that the efficient total heat recovery central air conditioner has high heat recovery quantity and high heat-recovery water outlet temperature.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a high-efficiency total heat recovery central air conditioner with energy-saving effect. Background technique [0002] When the existing high-efficiency total heat recovery central air conditioner works under the condition of low ambient temperature and heat recovery inlet water temperature, a large amount of refrigerant will accumulate in the condenser, resulting in insufficient refrigerant circulating in the system. Before the throttling device No subcooling. If additional refrigerant is added at this time, when the high-efficiency total heat recovery central air conditioner is running at high ambient temperature and heat recovery is not turned on, the high pressure of the high-efficiency total heat recovery central air conditioner will increase, and even lead to high-pressure protection. If no additional refrigerant is added at this time, the high-efficiency total heat recovery c...
