Problems solved by technology

The disadvantage of this method is that the system robustness is weakened due to the fixed compressor speed, and because the heat pump system has a relatively long stabilization time, the PTC is not started as soon as possible, resulting in poor comfort

Abstract

The invention discloses a compressor of a direct heat pump system and a PTC control method in the technical field of electric automobile heat pump air conditioners. The compressor comprises an air blower, an evaporation core body, a heat pump core body, a PTC heater, an evaporator temperature sensor, a main driving side temperature sensor, a co-driving side temperature sensor, an air conditioner unit and a heat pump system compressor. The air blower, the evaporation core body, the heat pump core body and the PTC heater are sequentially arranged in the air conditioner box in the airflow direction. The evaporator temperature sensor is arranged in the air conditioner box and located between the evaporation core body and the heat pump core body. The target rotating speed of the heat pump system compressor is controlled through the target air outlet temperature calculated through a comfort degree algorithm and the feedback temperature of the main driving side temperature sensor and the co-driving side temperature sensor; the PTC heater is divided into a left area and a right area to be independently controlled, and the target air outlet temperature of the PTC heater is 1.5 DEG C lower than the target air outlet temperature calculated through a comfort degree algorithm. Due to the fact that the PTC response is fast, the air outlet temperature of the system is made to be close to the target air outlet temperature fast, and the comfort requirement is met.

Description

Technical field [0001] The present invention relates to a control method of the art automotive heat pump an electric, in particular a PTC for the heat pump system and a method for controlling a compressor and a direct heat pump system PTC differentiation control. Background technique [0002] When the electric car winter heat pump system, heat pump system is often affected by ambient temperature, humidity, outdoor heat exchanger frost, affecting the system pressure as a result of insufficient heating performance, the current mainstream electric vehicle heat pump system will increase the positive temperature coefficient PTC fever It is to supplement heating, electric vehicles to meet the winter driving safety and comfort. However, since the car air conditioner tank internal space constraints, only the temperature sensor is mounted in the outlet temperature feedback to PTC. How to use this set of temperature sensors to control the two systems become difficult to control the heat pu...
