Split type non-pressure and full-automatic solar water heater

Abstract

The present invention relates to a split-type non-bearing automatic solar heater, which consists of a hot water storage box and a heat collector, which are connected to each other through a counter-flow heat conducting pipe. The normal working status of the hot water storage box presents in a non-bearing opened heat collection status and a non-bearing closed water supply status; the conversion of the two working statuses are controlled by the opening / closing of a user terminal water valve, and the on / off of a flow-rate sensing switch is triggered, and the on / off of the water inlet control valve, the off / on of the releasing control valve, and the off / on of the counter-flow heat conducting control valve are further controlled; the normal working status of the heat collector is the non-bearing opened status. With the solar heater, not only the functions of the bearing solar heater such as simple operation, strong water outgoing and no installation height requirements can be realized, but also the cost advantages of the non-bearing solar heater can be realized, thereby being suitable to be popularized in the market.

Description

technical field [0001] The invention relates to a split type non-pressure fully automatic solar water heater, which belongs to the application field of solar heat utilization. Background technique [0002] According to the working pressure, solar water heaters can be divided into two types: pressurized solar water heaters and non-pressurized solar water heaters. The advantages of pressure-bearing solar water heaters are simple operation, powerful water outlet, detachable design, and no installation height requirements. The disadvantage is that due to pressure-bearing design and operation, the manufacturing cost of water heaters is high, which is not conducive to market promotion and popularization; Solar water heaters have installation height requirements, low water outlet pressure, small water flow, difficult to reconcile hot and cold water, and complicated operation. The advantage is that due to the non-pressure design and operation, the manufacturing cost of the water hea...
