Problems solved by technology

Although the room air temperature and humidity play a very important role in the thermal comfort of the room, it is incomplete to characterize the thermal comfort in the room only by air temperature and humidity.

Embodiment 1

[0056] By default, the PMV value control interval for thermal comfort is set to [-0.5, +0.5], taking air conditioning as an example:

[0057] 1) When the PMV value>0.5, it indicates that the temperature is too high, and a cooling control command is issued;

[0058] 2) When -0.5≦PMV value≦0.5, it indicates that the temperature is suitable and there is no need to issue temperature control instructions;

[0059] 3) When the PMV value <-0.5, it indicates that the temperature is low, and a temperature rise control command is issued;

[0060] 4) In the cooling stage of the air conditioner, the PMV control interval is biased towards the warm side, that is, [0, +0.5];

[0061] 5) If the user enters deep sleep or deep sleep, the PMV control interval can be adjusted to [0, +1];

[0062] If the user intervenes, the PMV control interval is adjusted by comparing with the current PMV value and the user's upward or downward adjustment behavior.

[0063] In summary, the present invention i...

Abstract

The invention specifically relates to a comfort control method of a hotel room air conditioner. The method comprises the following steps of: determining an indoor average radiation temperature according to regions, dates, outdoor weather conditions and peripheral protection structure parameters; determining the metabolic rate of a human body according to light perception and time; calculating a PMV value according to indoor temperature, indoor relative humidity, the average radiation temperature and the metabolic rate of the human body; determining a PMV interval; comparing the PMV value with the PMV interval and issuing an air conditioning control instruction. The PMV target value is set to one side in the hotter direction during indoor refrigeration and to one side in the cooler direction during heating, the PMV control interval is timely adjusted according to different sleep stages after human body sleep, and therefore excessive energy consumption is inhibited within the comfort range, and the reduction of air conditioning load and energy conservation are realized. The PMV control interval is corrected in time to achieve energy-saving comfort control after user intervention isreceived.

Description

technical field [0001] The invention belongs to the technical field of air conditioning control, and in particular relates to a method for controlling the comfort level of an air conditioner in a hotel room. Background technique [0002] China's hotel energy consumption accounts for about 13% of the total energy consumption of the whole society, which is about double the international level. Air conditioning accounts for more than half of the energy consumption of hotels. Therefore, reducing energy consumption of air conditioning is an important goal for hotels to achieve energy conservation and emission reduction. . And data show that 67% of hotel guests are used to setting the temperature below 20 degrees. Energy saving and comfort sometimes have opposite aspects. In order to balance energy saving and thermal comfort, many literatures have studied how to achieve energy saving by suppressing excess energy consumption within the comfort range. As an example, there is known...
