Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] The heat pump air conditioner is based on an ordinary air conditioner, and a four-way reversing valve is installed. By changing the operation of the valve, the functions of the evaporator and condenser of the original air conditioner can be reversed, so that the cooling room An air conditioner that changes the function of air to a func...

Abstract

The embodiment of the invention provides a control method of a heat pump type air conditioner, and the heat pump type air conditioner. The control method comprises the steps that the runnable frequency range of an air conditioner compressor is determined according to the outdoor ambient temperature, the running frequency of the compressor is controlled to be within the runnable frequency range, system failure caused by the excessively high or excessively low frequency of the compressor is avoided, the current indoor temperature is checked, whether the temperature reaches the preset target indoor temperature or not is judged, and if yes, the temperature of an internal tube is adjusted. When the temperature meets the demands, the vertical temperature difference is decreased by adjusting thetemperature of the internal tube of the air conditioner, and comfortableness is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of air conditioning control, and in particular to a control method of a heat pump air conditioner and a heat pump air conditioner. Background technique [0002] In recent years, the heat pump air conditioner industry has gradually developed. Heat pump split air conditioners have basically completely replaced single cooling air conditioners and entered the home improvement market. With the frequency conversion of air conditioning products, frequency conversion heat pump air conditioners have become the mainstream of current air conditioning products. However, despite the rapid development of heat pump air conditioners, there are still many problems in the actual use process of users. There are various problems in the air conditioner products of major manufacturers. In the heating mode, there is a pain point in the industry, that is, the heating and air supply are uncomfortable, and th...
