Abstract

The invention discloses a double-plate exchange condensation water recycling high efficiency solar heat pump machine set, which comprises a refrigerating agent circulation system, a chilled water and heat collection hot water circulation system, a domestic hot water circulation system and a condensation water recycling and solar hot water auxiliary heat collection circulation system. The machine seat compensates the shortcomings of the common solar energy utilizing mode, gives full play to respective advantages, is capable of greatly utilizing heat in renewable resources and waste heat resources, effectively saves primary energy required by cold-hot water and hot water supply in an air conditioning, thereby being energy-saving and meeting the requirements for high-quality life, energy conversation and environment protection. Further, the machine set integrally designs the air conditioning and a water heater, achieves the aim of one set of equipment for two use functions, thereby beingfavorable for being popularized in families. Simultaneously, the machine set is simple and ingenious in structure, convenient to achieve and low in cost.

Description

【Technical field】 [0001] The invention relates to a high-efficiency solar heat pump unit for exchanging condensed water and recovering double plates, and the technology belongs to the fields of solar energy utilization, heat pump air conditioning and heat pump hot water. 【Background technique】 [0002] In recent years, the area of ​​commercial housing has exceeded 100m 2 The above-mentioned residences and duplex residences continue to increase, and the gap between large-scale central air-conditioning systems and household air-conditioning is revealed. Small-scale central air-conditioning combines the advantages of traditional central air-conditioning and household air-conditioning. Compared with traditional central air-conditioning, in It has advantages in space utilization, installation and energy saving. my country's small central air conditioners follow the road of "water system", and the main development is the type of chilled water (heat pump) unit. The transmission me...
