Abstract

<P>PROBLEM TO BE SOLVED: To perform thermal circulation and ventilation by preventing freezing of a water (water cooling) air conditioner combining the advantages of floor heating and 24 hour ventilating system by a heat pump (HP) hot water feeder, a gas hot water feeder, and an electric water heater to effect thermal circulation and ventilation, and making energy saving and environment protection compatible with each other. <P>SOLUTION: A fog nozzle valve 19 of a water cooling conditioner, an air filter 20, and the ventilation duct of an air duct 14 are situated after a flow water tank 5. The water cooling air conditioner to generate a water flow by the fog nozzle valve by using city water CW and regulate humidity by fog and minus ion, and the HP hot water feeder are interconnected through a blast duct 39, and cold air C heat- absorbed by the HP hot water feeder is fed in a room through the ventilation duct of the air conditioner. In the winter, hot air of the water cooling air conditioner is utilized as the heat of hot water of the HP hot water feeder. By improving a point that, in the summer, floor heating by the HP hot water feeder, the gas hot water feeder, or the electric water heater is not utilized, city water is caused to effect reverse flow to a floor heating unit and to utilize city water as support for cooling. <P>COPYRIGHT: (C)2003,JPO

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the prior application's reference number 001.
It is an invention proposal to improve each of the above, and to combine them with the heat pump water heater, which has recently been attracting attention, to make up for each advantage and improve the performance. In addition, the floor heating 41, which is used in the heat pump water heater 33, the gas water heater, the electric water heater, and the like, is used only for heating in winter and is not used in the hot summer, and the floor heating 41 It is an invention devised for the purpose of saving energy, improving the performance of each device, and protecting the environment by using as a supplement for air conditioning in the summer. The reference number 001 of the prior application is that the fog nozzle valve 19 and the air filter 2 are provided in front of the running water tank 5.
0, ventilation duct 22 was installed. Although it does not affect summer, it does not use water when it gets cold in winter or in the morning. There is a risk of a situation. Therefore, as shown in FIG. 1, the fog nozzle valve 19, the air filter 20, and the ventilation duct 22.
Is installed after flowing through the running water tank 5 to prevent the air conditioning heating in the winter from drying and adjust the humidity. The running water tank 5 which is filled up with is heavy and may be difficult to install. Therefore, the flowing water tank 5 radiates heat without covering the condenser with the radiation fins.
The heat absorption is conventionally performed in the atmosphere, and another big element of the present invention, which is dry air in winter, is heated by an air conditioner,
It is dried more and more, and it leads to rough skin, throat, nose, etc. Connect the tap water port (pipe) to the outdoor unit 3 so that the Then, in the same manner, attach the air duct 14 and attach the air filter 20. In addition, recent houses have high airtightness to save energy, and the glass has become double glass. Therefore, the room is ventilated with a 24-hour ventilation system.
It is important to take measures against condensation, mold and mites. Therefore, we recently considered the heat circulation and ventilation of the whole house by combining a hot pump water heater and a water air conditioner, which have been attracting attention, as a set of air conditioning, hot water supply and ventilation. First, the heat pump water heater (HP) absorbs heat in the atmosphere, It is released into the atmosphere. Then, in the summer, guide the air duct 39 from the HP water heater 33 to the air filter 20 of the air conditioner outdoor unit 3 and from the air duct 14.
Air is blown from the indoor unit 1 into the room to help save energy as a cooling aid. And from the room where the air conditioner such as the living room and the bedroom is installed,
Toilet exhaust duct 3 to exhaust air from the toilet and bathroom
5 and the bathroom exhaust duct 36, and through the exhaust duct 38, exhaust from the exhaust switching valve 34 at the inlet of the HP water heater 33. As a result, the smell of the toilet and the hot air and humidity of the bathroom do not stay inside. In addition, in the summertime, when the cooling operation is performed by the water air conditioner, the inside of the running water tank 5 The hot water is used by the HP water heater 33 to save energy. In winter, the air duct 3 of the HP water heater 33
HP cold air at the entrance of 9 I will.

The indoor unit 1 sends warm air to an air-conditioning room such as a living room or a bedroom, and together with other hot air such as a stove or floor heating, a toilet exhaust duct 35 from the toilet and the bathroom.
Then, while warming the toilet and the bathroom through the bathroom exhaust duct 36, it is guided to the HP water heater 33 through the exhaust duct 38. This will reduce the temperature difference in the winter in the house without installing auxiliary heating in the toilet or bathroom. Moreover, the hot air guided to the HP water heater 33 is more environmentally friendly as it can boil hot water more efficiently than it absorbs heat from the cold atmosphere and does not remove heat from the atmosphere.

Since it uses, it is not completely energy-saving.
However, better heat circulation and ventilation can be achieved by combining the heat pump water heater (HP), water air conditioner and 24-hour ventilation system. In addition, the floor heating 41, the heat pump water heater (HP) 33, the gas water heater, the electric water heater, and the like, which are hot topics, are combined with the water air conditioner in the winter. Water heater, The water supply pipe 42 which connects with is connected. Then, a floor heating valve 43 is provided at the inlet of the floor heating 41 of the HP water heater 33, the gas water heater, and the electric water heater, a pipe is provided between this and the return pipe, and a floor cooling valve 44 is provided at the outlet thereof. . Also,
A floor heating connection valve 45 is provided at a place where the floor heating unit 41 and the water supply pipe 42 are connected.

Set up.

Through the water supply adjustment valve 40 to adjust the flow water tank 5
Send to. Then, heat is absorbed in the running water tank 5, and the air is blown from the indoor unit 1 of the air conditioner as heating.

Water is sent to the electric water heater to become hot water and also for floor heating. The hot air heated by the air conditioner is sent to the living room, bedroom, etc., and is passed through the toilet or bathroom by a 24-hour ventilation system or the like, and the HP water heater 33 Next, in the summer, the floor heating valve 43 is closed, the floor cooling valve 44 is opened, and the water supply adjusting valve 40 causes the water supply pipe 42 to be connected by water pressure. After passing through, it passes through the floor cooling valve 44, absorbs heat, returns to the floor heating unit, and acts as an aid for cooling in the summer. This will reduce the cooling temperature in the summer and save energy. By the way, in the winter, fog is sent from the fog nozzle valve 19 to adjust the humidity, but if the air conditioner is stopped as it is, the indoor temperature will drop, causing condensation. Therefore, the air in the room warmed up by the heating is changed to 10 after the air conditioner is stopped.
For 15 minutes, the flap of the indoor unit 1 is closed to perform cooling operation to dehumidify and prevent dew condensation, and cool air is discharged from the exhaust duct 21 of the air duct 14 to the outdoor unit 3.
The dehumidified water is also drained outside the room through the drain hose 23. 24 Improvement of the water (water cooling) air conditioner, heat pump water heater 33, gas water heater, electric water heater, etc.
It is an invention aimed at saving energy and protecting the environment by ventilation with a combination of heat circulation and ventilation.
