Double-cold source heat pump centralized type air conditioner device

Abstract

The invention relates to a double-cold source heat pump centralized air conditioning apparatus, pertaining to air conditioner system energy efficient technology field. The inventive system includes a cooling water system, a secondary refrigerant water system, a chilled water system, an end air-processing system, a double-cold source heat pump air conditioning apparatus, and a plate heat exchanger. The cooling water system connects to the water cooling condenser in the double-cold source heat pump air conditioning apparatus. The secondary refrigerant water system respectively connects to the evaporator, plate heat exchanger of the double-cold source heat pump air conditioning apparatus, separately used for heat exchange with the cooling water system and chilled water system. The chilled water system connects to the plate type heat exchanger for heat exchange with the secondary refrigerant water system and conveying energy to air conditioner wind system by the end air-processing system. Finally the energy is conveyed to desired position by air pipes. The inventive system can avoid energy consumption height, which reduces operation electric charge and reduce peak load of electric network, thus excellent social benefit and economic benefit are obtained.

Description

technical field [0001] The invention relates to a system in the energy-saving technical field of a centralized air-conditioning system, in particular to a dual-cold-source heat pump centralized air-conditioning device. Background technique [0002] At present, the heat pump hosts of centralized air-conditioning systems used in the market all have a single cooling method, and use air source, water source or ground source as the cooling method. Among them, the air source heat pump is energy-saving and easy to install, and does not require a dedicated machine room. Small land and other advantages, so it is widely used in office buildings, shopping malls, hotels, etc. in the city center. The air source heat pump consumes electric energy during operation; if the air source heat pump is used as the main engine in the ice storage system, it cannot be popularized due to its low efficiency and poor economy when operating under ice storage conditions. Moreover, the ice-storage centra...
