Abstract

The invention discloses an air source hot water machine system and a control method thereof. The air source hot water machine system comprises a condenser, a four-way valve, a shell and tube heat exchanger, an electronic expansion valve, an inverter compressor, an outdoor fan, a water mixer, a first electronic flow valve, a second electronic flow valve, a controller, a first temperature sensor, a second temperature sensor and a third temperature sensor. One end of the first electronic flow valve is connected with a water outlet pipe of the condenser, and the other end of the first electronic flow valve is connected with the water mixer. One end of the second electronic flow valve is connected with a tap water pipe, and the other end of the second electronic flow valve is connected with the water mixer. The controller is used for controlling the inverter compressor and the outdoor fan according to the temperature detected by the first temperature sensor, so that the inverter compressor operates according to a preset frequency corresponding to the current environment temperature, and the outdoor fan operates according to a preset rotation speed corresponding to the current environment temperature. The controller is further used for controlling the open degree of the first electronic flow valve and the open degree of the second electronic flow valve according to the temperature detected by the second temperature sensor and the temperature detected by the third temperature sensor.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to an air source water heater system and a control method thereof. Background technique [0002] As we all know, there are currently air source water heaters on the market, but there are mainly two types of products: circulating water heaters and direct heating water heaters. The circulating hot water machine takes hot water for a long time and cannot supply hot water continuously; while the existing direct heating water machine is used in the northern region where the ambient temperature is low, due to the low temperature of the incoming water, the heating capacity is also low , but the outlet water temperature should still be kept at 55 degrees, so the water flow is very small, and it is prone to insufficient hot water. In addition, when defrosting the shell-and-tube heat exchanger of the existing direct-heating water heater, in order to prevent the condenser from freezing, two s...
