Are you running a hot spring with a free-flowing source, but not draining the lukewarm hot spring water as it is? It's a bathing facility, but are you carelessly draining large amounts of lukewarm bathwater? That wastewater still has value! You might be able to reuse the heat with a heat pump system! By extracting heat from the lukewarm hot spring to warm the source, or by capturing heat from the water being discarded to assist with the facility's hot water supply, the eco multi-heat pump reuses energy without waste. Not discarding means energy savings. Not discarding means reduced running costs. Not discarding means ecology.

• Wells and hot springs

Conventional heat pumps could not accommodate the water quality of baths, so they produced high-temperature hot water and maintained the bath's temperature through a heat exchanger. The new product now allows for direct heating of the circulating water in the bath through a combination of a newly developed heat exchanger unit and a heat pump unit. With the realization of direct heating, it achieves energy-efficient operation, and since a buffer tank and circulation pump are no longer necessary, it can be introduced at a lower cost and in a more compact form compared to conventional systems. The sales area is continuously expanding, so customers outside of the Kanto region are encouraged to inquire.

●Heat recovery type heat pumps are attracting attention as alternatives to boilers and chillers because they can efficiently utilize both waste heat from cold and hot sources that would otherwise be discarded. Government subsidy policies are also beginning to improve. ●There are two types of heat recovery type heat pumps: ・Heat recovery type heat pump A type that recovers heat from industrial wastewater or hot spring discharge for heating or hot water supply. ・Simultaneous extraction heat pump for cold and hot water A type that can efficiently supply both cooling and heating when both are needed simultaneously, such as in production processes or for air conditioning and hot water supply. ●While simultaneous extraction heat pumps for cold and hot water have significant advantages, building the system requires experience and know-how. Please make use of our expertise.

"Water bath for sauna" - Bathtub filtration system - Cooling heat source system (chiller) - Pressure-type water level control ● Reasons to recommend a filtration system for the water bath The water bath has a low temperature, which makes it easy for dirt such as sweat and sebum to coagulate, resulting in cloudiness. Without a filtration system, it quickly becomes cloudy, necessitating frequent replacement and cleaning of the bathwater. This leads to increased labor for cleaning and higher water bills. The municipal water supply (tap water) experiences temperature fluctuations depending on the season. Even in standard regions, there can be a temperature variation from 9°C in winter to 30°C in summer. The equipment needed to keep the supply water cold and constant incurs significant initial costs, installation space requirements, and running costs, which is similar for cold water showers. The initial costs of installing a filtration system are not much different. When a filtration system is installed, it only needs to cool down the water that has warmed up from bathing, so the actual running costs are not very high. Additionally, since the water bill only accounts for the water that evaporates or is lost from the body after initially filling the bath, it can also help reduce water costs.

During disasters, the temporary baths provided by the Self-Defense Forces are well-known, but due to limited availability, it is not guaranteed that everyone will be able to take a bath. Therefore, Hoshino General Trading, a specialized trading company in disaster prevention, has released a disaster prevention bath set. This set includes our circulation filtration device, Bathtime 24, as well as a one-touch tent, a round assembly water tank that serves as a bathtub, and a 5.0 kVA gasoline generator. You may be concerned that if many people use the bath, it will become dirty and require a large amount of water, but there is no need to worry. Bathtime 24 circulates and filters the water in the bathtub, so you can use it with just about 1 ton of water prepared initially. Additionally, chlorine tablets are included in the set, allowing for proper hygiene management. Furthermore, it is more affordable and can be stored compactly compared to conventional products. The disaster prevention bath set comes with two tents: one for changing and one for bathing. The changing room tent has a privacy curtain that prevents visibility from the entrance, ensuring that women can use it with peace of mind.

• Water Treatment

A system specialized for outdoor hot springs Generally, outdoor hot springs experience a drop in water temperature due to heat dissipation. In this case, it was predicted that the water temperature would decrease by 3 degrees in one hour, so we proposed a system that efficiently maintains the temperature and also incorporates a filtration function. Although it uses a "heat exchanger method," it combines a heat exchanger with a dedicated heat source unit and utilizes a small household filtration device suitable for the bathtub capacity. By controlling the dedicated heat source unit and the small filtration device in tandem, we created a very compact system that eliminates the need for large hot water supply equipment, unnecessary pumps, and expansion tanks. This system not only keeps the water clean at all times but also maintains a comfortable temperature without cooling down.

The "eco multi-hipon" is a heat pump system that reuses energy without waste. It's a waste to discard heat when using a cooling-only chiller. We propose a system that cleverly saves energy by combining it with existing chillers based on the concept of pre-cooling. We offer suitable proposals with a lineup of four types according to the cooling load situation.

The "eco Multi Heat Pump" is a heat pump system that reuses energy without waste. It is recommended for those struggling with insufficient cooling capacity of cooling towers due to extreme heat. Many are relying on well water or municipal water, but managing this is challenging. While they truly want to resolve the issue, it's only a short-term problem during the summer, so they cannot justify investing in equipment solely for the purpose of addressing the capacity shortage... Good news for such customers: consider the eco Multi Heat Pump, which can resolve cooling capacity shortages while also saving energy.

■ Air-cooled simultaneous extraction type (AW-F) While maximizing the use of exhaust heat, it supports both cooling-only load periods and heating-only load periods with six operating modes. We propose the best energy-saving system. In factories and facilities using air-cooled chillers, the warm air discharged from the air heat exchanger is like wasting energy. Discharge at temperatures higher than the cooling tower or supply water temperature also wastes energy. By effectively recovering heat, energy savings and cost reductions can be achieved.
